    Before WOLLMAN, LOKEN, and COLLOTON, Circuit Judges.
    ____________
    LOKEN, Circuit Judge
    The issue is whether the Eighth and Fourteenth Amendments, as applied, bar
    Missouri officials from employing a procedure that is authorized by Missouri statute
    to execute Russell Bucklew.
    In March 2006, Bucklew stole a car; armed himself with pistols, handcuffs, and
    a roll of duct tape; and followed his former girlfriend, Stephanie Ray, to the home of
    Michael Sanders, where she was living. Bucklew knocked and entered the trailer
    with a pistol in each hand when Sanders’s son opened the door. Sanders took the
    children to the back room and grabbed a shotgun. Bucklew began shooting. Two
    bullets struck Sanders, one piercing his chest. Bucklew fired at Sanders’s six-year-
    old son, but missed. As Sanders bled to death, Bucklew struck Ray in the face with
    a pistol, handcuffed Ray, dragged her to the stolen car, drove away, and raped Ray
    in the back seat of the car. He was apprehended by the highway patrol after a
    gunfight in which Bucklew and a trooper were wounded.
    A Missouri state court jury convicted Bucklew of murder, kidnaping, and rape.
    The trial court sentenced Bucklew to death, as the jury had recommended. His
    conviction and sentence were affirmed on direct appeal. State v. Bucklew, 
    973 S.W.2d 83
    (Mo. banc 1998). The trial court denied his petition for post-conviction
    relief, and the Supreme Court of Missouri again affirmed. Bucklew v. State, 
    38 S.W.3d 395
    (Mo. banc 2001). We subsequently affirmed the district court’s denial
    of Bucklew’s petition for a federal writ of habeas corpus. Bucklew v. Luebbers, 
    436 F.3d 1010
    (8th Cir. 2006). The Supreme Court of Missouri issued a writ of execution
    for May 21, 2014. Bucklew filed this action under 42 U.S.C. § 1983, alleging that
    execution by Missouri’s lethal injection protocol, authorized by statute, would
    constitute cruel and unusual punishment in violation of the Eighth and Fourteenth
    Amendments as applied to him because of his unique medical condition. Bucklew
    appeals the district court’s1 grant of summary judgment in favor of the state
    defendants because Bucklew failed to present adequate evidence to establish his
    claim under the governing standard established by the Supreme Court in Baze v.
    Rees, 
    553 U.S. 35
    (2008), and Glossip v. Gross, 
    135 S. Ct. 2726
    (2015). Reviewing
    the grant of summary judgment de novo, we affirm.

    The Honorable Beth Phillips, United States District Judge for the Western
    District of Missouri.

    I.
    Missouri’s method of execution is by injection of a lethal dose of the drug
    pentobarbital. Two days before his scheduled execution in 2014, the district court
    denied Bucklew’s motion for a stay of execution and dismissed this as-applied action
    sua sponte. On appeal, a divided panel granted a stay of execution, Bucklew v.
    Lombardi, 565 Fed. Appx. 562 (8th Cir. 2014); the court en banc vacated the stay.
    Bucklew applied to the Supreme Court for a stay of execution, and the Court issued
    an Order granting his application “for stay pending appeal in the Eighth Circuit.”
    This court, acting en banc, reversed the sua sponte dismissal of Bucklew’s as-applied
    Eighth Amendment claim and remanded to the district court for further proceedings.
    Bucklew v. Lombardi, 
    783 F.3d 1120
    , 1128 (8th Cir. 2015) (“Bucklew I”). On the
    same day, the en banc court affirmed the district court’s dismissal on the merits of a
    facial challenge to Missouri’s lethal injection protocol filed by several inmates
    sentenced to death, including Bucklew. Zink v. Lombardi, 
    783 F.3d 1089
    , 1114 (8th
    Cir.), cert denied, 
    135 S. Ct. 2941
    (2015).2

    “The doctrine of res judicata or claim preclusion bars relitigation of a § 1983
    claim if the prior judgment was a final judgment on the merits rendered by a court of
    competent jurisdiction, and if the same cause of action and the same parties or their
    privies were involved.” Baker v. Chisom, 
    501 F.3d 920
    , 925 (8th Cir. 2007), cert
    denied, 
    554 U.S. 902
    (2008). As Bucklew was a plaintiff in Zink, any facial
    challenge to the current method of execution in this case is precluded. Defendants
    argue that Bucklew’s as-applied challenge is also precluded because it could have
    been raised in Zink. See Brown v. St. Louis Police Dep’t, 
    691 F.2d 393
    , 396 (8th Cir.
    1982). Like the district court, we decline to address this complex issue. See Bucklew
    
    I, 783 F.3d at 1122
    n.1; cf. Whole Woman’s Health v. Hellerstedt, 136 S. Ct 2292,
    2305 (2016). We likewise decline to address defendants’ claim that Bucklew’s as-
    applied challenge is barred by the applicable statute of limitations. See Boyd v.
    Warden, Holman Corr. Facility, 
    856 F.3d 853
    , 874-76 (11th Cir. 2017).
    -3-
    Our decision in Bucklew I set forth in considerable detail the allegations in
    Bucklew’s as-applied complaint regarding his medical 
    condition. 783 F.3d at 1124
    -
    26. Bucklew has long suffered from a congenital condition called cavernous
    hemangioma, which causes clumps of weak, malformed blood vessels and tumors to
    grow in his face, head, neck, and throat. The large, inoperable tumors fill with blood,
    periodically rupture, and partially obstruct his airway. In addition, the condition
    affects his circulatory system, and he has compromised peripheral veins in his hands
    and arms. In his motion for a stay of execution in Bucklew I, Bucklew argued:
    Dr. Joel Zivot, a board-certified anesthesiologist . . . concluded after
    reviewing Mr. Bucklew’s medical records that a substantial risk existed
    that, because of Mr. Bucklew’s vascular malformation, the lethal drug
    will likely not circulate as intended, creating a substantial risk of a
    “prolonged and extremely painful execution.” Dr. Zivot also concluded
    that a very substantial risk existed that Mr. Bucklew would hemorrhage
    during the execution, potentially choking on his own blood -- a risk
    greatly heightened by Mr. Bucklew’s partially obstructed airway.
    *    *   *     *   *
    [The Department of Corrections has advised it would not use a dye in
    flushing the intravenous line because Dr. Zivot warned that might cause
    a spike in Bucklew’s blood pressure.] Reactionary changes at the
    eleventh hour, without the guidance of imaging or tests, create a
    substantial risk to Mr. Bucklew, who suffers from a complex and severe
    medical condition that has compromised his veins.
    *    *   *     *   *
    The DOC seems to acknowledge they agree with Dr. Zivot that Mr.
    Bucklew’s obstructed airway presents substantial risks of needless pain
    and suffering, but what they plan to do about it is a mystery. Will they
    execute Mr. Bucklew in a seated position? . . . The DOC should be
    required to disclose how it plans to execute Mr. Bucklew so that this
    Court can properly assess whether additional risks are present. . . . Until
    -4-
    Mr. Bucklew knows what protocol the DOC will use to kill him, and
    until the DOC is required to conduct the necessary imaging and testing
    to quantify the expansion of Mr. Bucklew’s hemangiomas and the extent
    of his airway obstruction, it is not possible to execute him without
    substantial risk of severe pain and needless suffering.
    Defendants’ Suggestions in Opposition argued that Bucklew’s “proposed changes . . .
    with the exception of his complaint about [dye], which Missouri will not use in
    Bucklew’s execution, are not really changes in the method of execution.”
    Glossip and Baze established two requirements for an Eighth Amendment
    challenge to a method of execution. First, the challenger must “establish that the
    method presents a risk that is sure or very likely to cause serious illness and needless
    suffering, and give rise to sufficiently imminent dangers.” 
    Glossip, 135 S. Ct. at 2737
    (emphasis in original), citing 
    Baze, 553 U.S. at 50
    . This evidence must show that the
    pain and suffering being risked is severe in relation to the pain and suffering that is
    accepted as inherent in any method of execution. 
    Id. at 2733.
    Second, the challenger
    must “identify an alternative that is feasible, readily implemented, and in fact
    significantly reduces a substantial risk of severe pain.” 
    Glossip, 135 S. Ct. at 2737
    ,
    citing 
    Baze, 553 U.S. at 52
    . This two-part standard governs as-applied as well as
    facial challenges to a method of execution. See, e.g., Jones v. Kelley, 
    854 F.3d 1009
    ,
    1013, 1016 (8th Cir. 2017); Williams v. Kelley, 
    854 F.3d 998
    , 1001 (8th Cir. 2017);
    Johnson v. Lombardi, 
    809 F.3d 388
    , 390 (8th Cir. 2015); Bucklew 
    I, 783 F.3d at 1123
    , 1127. As a panel we are bound by these controlling precedents. Bucklew
    argues the second Baze/Glossip requirement of a feasible alternative method of
    execution that substantially reduces the risk of suffering should not apply to “an
    individual who is simply too sick and anomalous to execute in a constitutional
    manner,” like those who may not be executed for mental health reasons. See, e.g.,
    Ford v. Wainwright, 
    477 U.S. 399
    , 410 (1986). The Supreme Court has not
    recognized a categorical exemption from the death penalty for individuals with
    physical ailments or disabilities. Thus, in the decision on appeal, the district court
    -5-
    properly applied the Baze/Glossip two-part standard in dismissing Bucklew’s as-
    applied claim.
    We concluded in Bucklew I, based on a record “which went well beyond the
    four corners of Bucklew’s complaint,” that the complaint’s allegations, bolstered by
    defendants’ concession “that the Department’s lethal injection procedure would be
    changed on account of his condition by eliminating the use of methylene blue dye,”
    sufficiently alleged the first requirement of an as-applied challenge to the method of
    execution -- “a substantial risk of serious and imminent harm that is sure or very
    likely to 
    occur.” 783 F.3d at 1127
    . We further concluded the district court’s sua
    sponte dismissal was premature because these detailed allegations made it
    inappropriate “to assume that Bucklew would decline an invitation to amend the as-
    applied challenge” to plausibly allege a feasible and more humane alternative method
    of execution, the second requirement under the Baze/Glossip standard. 
    Id. In remanding,
    we directed that further proceedings “be narrowly tailored and
    expeditiously conducted to address only those issues that are essential to resolving”
    the as-applied challenge. 
    Id. at 1128.
    We explained:
    Bucklew’s arguments on appeal raise an inference that he is
    impermissibly seeking merely to investigate the protocol without taking
    a position as to what is needed to fix it. He may not be “permitted to
    supervise every step of the execution process.” Rather, at the earliest
    possible time, he must identify a feasible, readily implemented
    alternative procedure that will significantly reduce a substantial risk of
    severe pain and that the State refuses to adopt. . . . Any assertion that all
    methods of execution are unconstitutional does not state a plausible
    claim under the Eighth Amendment or a cognizable claim under § 1983.
    
    Id. (quotation omitted;
    emphasis in original).
    -6-
    II.
    On remand, consistent with our directive, the district court first ordered
    Bucklew to file an amended complaint that adequately identified an alternative
    procedure. Twice, Bucklew filed amended complaints that failed to comply with this
    order. Given one last chance to comply or face dismissal, on October 13, 2015,
    Bucklew filed a Fourth Amended Complaint. As relevant here, it alleged:
    106. Based on Mr. Bucklew’s unique and severe condition, there
    is no way to proceed with Mr. Bucklew’s execution under Missouri’s
    lethal injection protocol without a substantial risk to Mr. Bucklew of
    suffering grave adverse events during the execution, including
    hemorrhaging, suffocating or experiencing excruciating pain.
    107. Under any scenario or with any of lethal drug, execution by
    lethal injection poses an enormous risk that Mr. Bucklew will suffer
    extreme, excruciating and prolonged pain -- all accompanied by choking
    and struggling for air.
    128. In May 2014, the DOC also proposed a second adjustment
    in its protocol, offering to adjust the gurney so that Mr. Bucklew is not
    lying completely prone.3 . . . As a practical matter, no adjustment would
    likely be sufficient, as the stress of the execution may unavoidably cause
    Mr. Bucklew’s hemangiomas to rupture, leading to hemorrhaging,
    bleeding in his throat and through his facial orifices, and coughing and
    choking on his own blood.
    129. In order to fully evaluate and establish the risks to Mr.
    Bucklew from execution by lethal injection, a full and complete set of
    imaging studies must be conducted.
    3
    In their answer to paragraph 128, defendants alleged: “Defendants admit that
    the Defendants offered to have the anesthesiologist position the angle of the gurney
    in a proper position.” Thus, this fact was established by the pleadings.
    -7-
    139. Mr. Bucklew is mindful of the Court’s directive to allege a
    feasible, readily implemented alternative procedure . . . . Mr. Bucklew
    has complied . . . by researching and proposing execution by lethal gas,
    which is specifically authorized by Missouri law and which Missouri’s
    Attorney General has stated the DOC is prepared to implement.
    150. In adherence with the pleading requirements set forth in
    Glossip, and as stated above, Mr. Bucklew specifically alleges lethal gas
    as a feasible and available alternative method that will significantly
    reduce the risk of severe pain to Mr. Bucklew.
    In other words, Bucklew took the position that no modification of Missouri’s lethal
    injection method of execution could be constitutionally applied to execute Bucklew.
    He proposed massive discovery allegedly needed to establish the first Baze/Glossip
    requirement. But his legal theory is that alternative procedures such as adjusting the
    gurney’s position are irrelevant because no lethal injection procedure would be
    constitutional, only a change to the use of lethal gas would be adequate.
    Bucklew’s as-applied claim focused on two aspects of his medical condition.
    First, Bucklew’s experts initially opined that his peripheral veins are so weak that
    injection of a lethal dose of pentobarbital would not adequately circulate, leading to
    a prolonged and painful execution. The district court concluded that discovery and
    expert opinions developed on remand refuted this claim. The lethal injection protocol
    provides that medical personnel may insert the primary intravenous (IV) line “as a
    central venous line” and may dispense with a secondary peripheral IV line if “the
    prisoner’s physical condition makes it unduly difficult to insert more than one IV.”
    Bucklew’s expert Dr. Zivot conceded, and Defendants’ expert, Dr. Joseph Antognini,
    agreed, that the central femoral vein can circulate a “fair amount of fluid” without
    serious risk of rupture and that Bucklew’s medical condition will not affect the flow
    of pentobarbital after it is injected through this vein.
    -8-
    Second, Bucklew’s experts opined that his condition will cause him to
    experience severe choking and suffocation during execution by lethal injection.
    When Bucklew is supine, gravity pulls the hemangioma tumor into his throat which
    causes his breathing to be labored and the tumor to rupture and bleed. When
    conscious, Bucklew can “adjust” his breathing with repeated swallowing that
    prevents the tumor from blocking his airway. But during the “twilight stage” of a
    lethal injection execution, Dr. Zivot opined that Bucklew will be aware he is choking
    on his own blood and in pain before the pentobarbital renders him unconscious and
    unaware of pain. Based on a study of lethal injections in horses, Dr. Zivot estimated
    there could be a period as short as 52 seconds and as long as 240 seconds when
    Bucklew is conscious but immobile and unable to adjust his breathing; his attempts
    to breath will create friction, causing the tumor to bleed and possibly hemorrhage.
    In Dr. Zivot’s opinion, there is a “very, very high likelihood” that Bucklew will suffer
    “choking complications, including visible hemorrhaging,” if he is executed by any
    means of lethal injection, including using the drug pentobarbital.
    According to Defendants’ expert, Dr. Antognini, pentobarbital causes death by
    “producing rapid, deep unconscious[ness], respiratory depression, followed by . . .
    complete absence of respiration, decreased oxygen levels, slowing of the heart, and
    then the heart stopping.” In contrast to Dr. Zivot, Dr. Antognini opined that
    pentobarbital would cause “rapid and deep unconsciousness” within 20-30 seconds
    of entering Bucklew’s blood stream, rendering him insensate to bleeding and choking
    sensations. Dr. Antognini also challenged Dr. Zivot’s opinion that a supine Bucklew,
    unable to adjust his breathing, will be aware he is choking on his own blood and in
    pain from the tumor blocking his airway before the pentobarbital renders him
    unconscious. Dr. Antognini noted that, between 2000 and 2003, Bucklew underwent
    general anesthesia eight times, at least once in a supine position. In December 2016,
    Bucklew lay supine for over an hour undergoing an MRI, with no more than
    discomfort. The MRI revealed that his tumor had slightly shrunk since 2010.
    -9-
    In granting defendants summary judgment, the district court declined to rely
    on the first Glossip/Baze requirement because these conflicting expert opinions
    “would permit a factfinder to conclude that for as long as four minutes [after the
    injection of pentobarbital Bucklew] could be aware that he is choking or unable to
    breathe but be unable [to] ‘adjust’ his breathing to remedy the situation.” Rather, the
    court held that Bucklew failed to provide adequate evidence that his alternative
    method of execution -- lethal gas -- was a “feasible, readily implemented” alternative
    that would “in fact significantly reduce a substantial risk of severe pain” as compared
    to lethal injection. 
    Glossip, 135 S. Ct. at 2737
    ; 
    Baze, 553 U.S. at 52
    .
    III.
    To succeed in his challenge to Missouri’s lethal injection execution protocol,
    Bucklew must establish both prongs of the Glossip/Baze standard. Glossip, 135 S.
    Ct. 2737. The district court held that Bucklew failed to establish the second prong
    of Glossip/Baze by showing that an alternative method of execution would “in fact
    significantly reduce a substantial risk of severe pain.” As noted, Bucklew argues the
    Glossip/Baze standard should not apply to an as-applied challenge to a method of
    execution, an argument our controlling precedents have rejected. He raises two
    additional issues on appeal.
    A. Bucklew first argues the district court erred in granting summary judgment
    on the second Glossip/Baze requirement because he presented sufficient evidence that
    his proposed alternative method of execution -- death through nitrogen gas-induced
    hypoxia -- “would substantially reduce his suffering.” Summary judgment is not
    appropriate when there are material issues of disputed fact, and the Supreme Court
    in Glossip made clear that this issue may require findings of fact that are reviewed for
    clear error. 
    See 135 S. Ct. at 2739-41
    (majority opinion) and 2786 (Sotomayor, J.,
    dissenting). However, whether a method of execution “constitutes cruel and unusual
    punishment is a question of law.” Swindler v. Lockhart, 
    885 F.2d 1342
    , 1350 (8th
    -10-
    Cir. 1989). Thus, unless there are material underlying issues of disputed fact, it is
    appropriate to resolve this ultimate issue of law by summary judgment.
    Nitrogen hypoxia is an authorized method of execution under Missouri Law.
    See Mo. Stat. Ann. § 546.720. Missouri has not used this method of execution since
    1965 and does not currently have a protocol in place for execution by lethal gas. But
    there are ongoing studies of the method in other States and at least preliminary
    indications that Missouri will undertake to develop a protocol. Defendants do not
    argue this is not a feasible and available alternative.
    The district court granted summary judgment based on Bucklew’s failure to
    provide adequate evidence that execution by nitrogen hypoxia would substantially
    reduce the risk of pain or suffering. The court allowed Bucklew extensive discovery
    into defendants’ knowledge regarding execution by lethal gas. But Missouri’s lack
    of recent experience meant that this discovery produced little relevant evidence and
    no evidence that the risk posed by lethal injection is substantial when compared to the
    risk posed by lethal gas. See 
    Glossip, 135 S. Ct. at 2738
    ; 
    Johnson, 809 F.3d at 391
    .
    Bucklew’s theory is that execution by nitrogen hypoxia would render Bucklew
    insensate more quickly than lethal injection and would not cause choking and
    bleeding in his tumor-blocked airway. But his expert, Dr. Zivot, provided no support
    for this theory. Dr. Zivot’s Supplemental Expert Report explained:
    [W]hile I can assess Mr. Bucklew’s current medical status and render an
    expert opinion as to the documented and significant risks associated
    with executing Mr. Bucklew under Missouri’s current Execution
    Procedure, I cannot advise counsel or the Court on how to execute Mr.
    Bucklew in a way that would satisfy Constitutional requirements.
    Lacking affirmative comparative evidence, Bucklew relied on Dr. Antognini’s
    deposition. In his Expert Report, Dr. Antognini concluded that “the use of lethal gas
    -11-
    would not significantly lessen any suffering or be less painful than lethal injection in
    this inmate.” At his deposition, Dr. Antognini was asked:
    Q. Why does lethal gas not hold any advantage compared to lethal
    injection.
    A. Well . . . there are a lot of types of gases that could be used
    . . . . [U]sing gas would not significantly lessen any suffering or be less
    painful. Because, again, their onset of action is going to be relatively
    fast, just like Pentobarbital’s onset -- onset of action.
    Q. That’s it? Simply because it would happen quickly?
    A. Correct.
    The district court concluded this opinion provided nothing to compare:
    Dr. Antognini specifically stated that he believed there would be no
    difference in the “speed” of lethal gas as compared to pentobarbital. . . .
    In the absence of evidence contradicting Defendants’ expert and
    supporting Plaintiff’s theory, there is not a triable issue.
    On appeal, Bucklew argues the district court should have compared Dr. Zivot’s
    opinion that lethal injection would take up to four minutes to cause Bucklew’s brain
    death with Dr. Antognini’s testimony that lethal gas would render him unconscious
    in the same amount of time as lethal injection, 20 to 30 seconds. But Dr. Antognini’s
    comparative testimony was that both methods would result in unconsciousness in
    approximately the same amount of time. Bucklew offered no contrary comparative
    evidence and thus the district court correctly concluded that he failed to satisfy his
    burden to provide evidence “establishing a known and available alternative that
    would significantly reduce a substantial risk of severe pain.” McGehee v.
    Hutchinson, 
    854 F.3d 488
    , 493 (8th Cir. 2017).
    -12-
    In addition, Bucklew’s claim that he will experience choking sensations during
    an execution by lethal injection but not by nitrogen hypoxia rests on the proposition
    that he could be seated during the latter but not the former. He argues there is
    evidence he will be forced to remain supine during an execution by lethal injection,
    when his tumor will cause him to sense he is choking on his own blood, whereas he
    could remain seated during the administration of lethal gas, which would not cause
    a choking sensation. But this argument lacks factual support in the record. Having
    taken the position that any lethal injection procedure would violate the Eighth
    Amendment, Bucklew made no effort to determine what changes, if any, the DOC
    would make in applying its lethal injection protocol in executing Bucklew, other than
    defendants advising -- prior to remand by this court -- that dye would not be used.
    Based on Bucklew’s argument to the en banc court, we expected that the core
    of the proceedings on remand would be defining what changes defendants would
    make on account of Bucklew’s medical condition and then evaluating that modified
    procedure under the two-part Baze/Glossip standard. On remand, Director of
    Corrections Ann Precythe testified that the medical members of the execution team
    are provided a prisoner’s medical history in preparing for the execution. Precythe has
    authority to make changes in the execution protocol, such as how the primary IV line
    will be inserted in the central femoral vein or how the gurney will be positioned, if
    the team advises that changes are needed. While Bucklew sought and was denied
    discovery of the identities of the execution team’s medical members, he never urged
    the district court to establish a suitable fact-finding procedure -- for example, by
    anonymous interrogatories or written deposition questions to the execution team
    members -- for discovery of facts needed for the DOC to define the as-applied lethal
    injection protocol it intends to use for Bucklew. As Bucklew did not pursue these
    issues, the pleadings established that defendants have proposed to reposition the
    gurney during Bucklew’s deposition, and Director Precythe testified that she has
    authority to make this type of change in the execution protocol based on the execution
    team’s advice based on review of Bucklew’s medical history, but the record does not

    disclose whether Bucklew will in fact be supine during the execution,4 nor does it
    disclose that a “cut-down” procedure will not be used to place the primary IV line in
    his central femoral vein, a procedure Dr. Antognini opined was unnecessary.
    Bucklew simply asserts that, in comparing execution by lethal injection and by lethal
    gas, we must accept his speculation that defendants will employ these risk-increasing
    procedures. This we will not do.
    Like the district court, we conclude the summary judgment record contains no
    basis to conclude that Bucklew’s risk of severe pain would be substantially reduced
    by use of nitrogen hypoxia instead of lethal injection as the method of execution.
    Evidence that “is equivocal, lacks scientific consensus and presents a paucity of
    reliable scientific evidence” does not establish that an execution is sure or very likely
    to cause serious illness and needless suffering. Williams v. 
    Kelley, 854 F.3d at 1001
    (quotation omitted). Therefore, he failed to establish the second prong of the
    Glossip/Baze standard.
    B. Bucklew further contends the district court erred in denying his requests for
    discovery relating to “M2” and “M3,” two members of the lethal injection execution
    team. Bucklew argues he was entitled to discovery of the medical technicians’
    qualifications, training, and experience because it would “illuminate the nature and
    extent of the risks of suffering he faces.” For example, if M3 was not qualified to
    safely place his IV in the central femoral vein, this would directly impact the risk of
    4
    Dr. Zivot surmised that Bucklew will be required to lie flat during lethal
    injection based on what he observed at an execution in Georgia. He gave no reason
    to believe that pentobarbital could not be injected through a femoral vein while
    Bucklew is seated. He merely opined that “[i]t’s more difficult” to administer an
    anesthetic to someone who is sitting up. Dr. Antognini, in addition to opining that
    Bucklew would be rendered unconscious and insensate within 20 to 30 seconds of
    pentobarbital injection, noted that it was not necessary that Bucklew be supine in
    order to inject pentobarbital in his femoral vein.

    pain and suffering. We review a district court’s discovery rulings narrowly and with
    great deference and will reverse only for a “gross abuse of discretion resulting in
    fundamental unfairness.” Marksmeier v. Davie, 
    622 F.3d 896
    , 903 (8th Cir. 2010).
    Bucklew’s argument proceeds from the premise that M2 and M3 may not be
    qualified for the positions for which they have been hired. But we will not assume
    that Missouri employs personnel who are incompetent or unqualified to perform their
    assigned duties. See Clemons v. Crawford, 
    585 F.3d 1119
    , 1128 (8th Cir. 2009). He
    further argues that deposition of M2 and M3 is necessary to understand how they will
    handle a circumstance in case something goes wrong during Bucklew’s execution.
    The potentiality that something may go wrong in an execution does not give rise to
    an Eighth Amendment violation. 
    Zink, 783 F.3d at 1101
    . “Some risk of pain is
    inherent in any method of execution -- no matter how humane -- if only from the
    prospect of error in following the required procedure. . . . [A]n isolated mishap alone
    does not give rise to an Eighth Amendment violation.” 
    Baze, 553 U.S. at 47
    , 50.
    Thus, the district court’s ruling was consistent with our instruction in remanding that
    Bucklew “may not be permitted to supervise every step of the execution process.”
    Bucklew 
    I, 783 F.3d at 1128
    (quotation omitted). The Baze/Glossip evaluation must
    be based on the as-applied pre-execution protocol, assuming that those responsible
    for carrying out the sentence are competent and qualified to do so, and that the
    procedure will go as intended.
    III. Conclusion
    Having thoroughly reviewed the record, we conclude that Bucklew has failed
    to establish that lethal injection, as applied to him, constitutes cruel and unusual
    punishment under the Eighth and Fourteenth Amendments. Therefore, we affirm the
    judgment of the district court.
    -15-
    COLLOTON, Circuit Judge, dissenting.
    Russell Bucklew alleges that the State of Missouri’s method of execution by
    lethal injection violates his rights under the Eighth and Fourteenth Amendments. He
    seeks an injunction prohibiting an execution by that method. The district court
    granted summary judgment for the State, but there are genuine disputes of material
    fact that require findings of fact by the district court before this dispute can be
    resolved. I would therefore remand the case for the district court promptly to conduct
    further proceedings.
    Bucklew’s claim under 42 U.S.C. § 1983 requires him to prove two elements:
    (1) that the State’s method of execution is sure or very likely to cause him severe
    pain, and (2) that an alternative method of execution that is feasible and readily
    implemented would significantly reduce the substantial risk of severe pain. Glossip
    v. Gross, 
    135 S. Ct. 2726
    , 2737 (2015); Bucklew v. Lombardi, 
    783 F.3d 1120
    , 1123,
    1128 (8th Cir. 2015) (en banc). On the first element, the district court concluded that
    taking the evidence in the light most favorable to Bucklew, there is a substantial risk
    under Missouri’s lethal injection protocol that Bucklew will experience choking and
    an inability to breathe for up to four minutes. On the second element, however, the
    court ruled as a matter of law that Bucklew’s suggested alternative
    method—execution by administration of nitrogen gas—would not significantly
    reduce the substantial risk that the court identified under the first element. In my
    view, the district court’s reasoning as to the first element is inconsistent with its
    summary disposition of Bucklew’s claim on the second.
    On the first element, Bucklew’s theory is that he will suffer severe pain by
    prolonged choking or suffocation if the State executes him by lethal injection. He
    contends that when he lies supine on the execution gurney, tumors in his throat will
    block his airway unless he can “adjust” his positioning to enable breathing. Bucklew
    -16-
    argues that if an injection of pentobarbital renders him unable to adjust his
    positioning while he can still sense pain, then he will choke or suffocate.
    In assessing that claim, the district court cited conflicting expert testimony
    from Bucklew’s expert, Dr. Joel Zivot, and the State’s expert, Dr. Joseph Antognini.
    Dr. Antognini testified that if the State proceeded by way of lethal injection using
    pentobarbital, then Bucklew would be unconscious within twenty to thirty seconds
    and incapable of experiencing pain at that point. R. Doc. 182-5, at 10, 40-41. Dr.
    Zivot, however, differed: “I strongly disagree with Dr. Antognini’s repeated claim
    that the pentobarbital injection would result in ‘rapid unconsciousness’ and therefore
    Mr. Bucklew would not experience any suffocating or choking.” R. Doc. 182-1, at
    147. Zivot opined that Bucklew “would likely experience unconsciousness that sets
    in progressively as the chemical circulates through his system,” and that “during this
    in-between twilight stage,” Bucklew “is likely to experience prolonged feelings of
    suffocation and excruciating pain.” 
    Id. In his
    deposition, Dr. Zivot opined that “there will be points,” before Bucklew
    dies, “where he’s beginning to experience the effects of the pentobarbital, where his
    ability to control and regulate and adjust his airway will be impaired, although there
    will still be the experience capable of knowing that he cannot make the adjustment,
    and will experience it as choking.” 
    Id. at 81.
    When directed to Dr. Antognini’s
    opinion that Bucklew would be unaware of noxious stimuli within twenty to thirty
    seconds of a pentobarbital injection, Dr. Zivot observed that Antognini’s opinion was
    based on a study involving dogs from fifty years ago and testified that his “number
    would be longer than that.” 
    Id. at 85.
    When asked for his “number,” Dr. Zivot
    pointed to a study on lethal injections administered to horses; he said the study
    recorded “a range of as short as fifty-two seconds and as long as about two hundred
    and forty seconds before they see isoelectric EEG.” 
    Id. at 85-86.
    Dr. Zivot noted that
    the “number” that he derived from the horse study was “more than twice as long as”
    the number suggested by Dr. Antognini. 
    Id. at 86.
    He defined “isoelectric EEG” as
    -17-
    “indicative of at least electrical silence on the parts of the brain that the
    electroencephalogram has access to.” 
    Id. The district
    court observed that “[a]n execution is typically conducted with the
    prisoner lying on his back,” and that the record “establishes that [Bucklew] has
    difficulty breathing while in that position because the tumors can cause choking or
    an inability to breathe.” The court understood Dr. Zivot to mean that “it could be
    fifty-two to 240 seconds before the pentobarbital induces a state in which [Bucklew]
    could no longer sense that he is choking or unable to breathe.” Thus, the court
    concluded that “construing the Record in [Bucklew’s] favor reveals that it could be
    fifty-two to 240 seconds before the pentobarbital induces a state in which [Bucklew]
    could no longer sense that he is choking or unable to breathe.” Again, the court
    reasoned that “the facts construed in [Bucklew’s] favor would permit a factfinder to
    conclude that for as long as four minutes [Bucklew] could be aware that he is choking
    or unable to breathe but be unable to ‘adjust’ his breathing to remedy the situation.”
    On that basis, the court presumed for purposes of the motion for summary judgment
    that “there is a substantial risk that [Bucklew] will experience choking and an
    inability to breathe for up to four minutes.”
    The State disputes that there is a genuine dispute of material fact on the first
    element of Bucklew’s claim, but the district court properly concluded that findings
    of fact were required. Bucklew pointed to evidence from Missouri corrections
    officials that prisoners have always laid flat on their backs during executions by lethal
    injection in Missouri. R. Doc. 182-7, at 10; R. Doc. 182-9, at 1; R. Doc. 182-12, at
    29, 91. One official testified that he did not know whether the gurney could be
    adjusted. R. Doc. 182-12, at 91. Another official believed that the head of the gurney
    “could” be raised (or that a gurney with that capability could be acquired), and that
    an anesthesiologist would have “the freedom” to adjust the gurney “if” he or she
    determined that it would be in the best medical interest of the offender to do so. R.
    Doc. 182-7, at 14. But the State did not present evidence about how it would position
    -18-
    Bucklew or the gurney during his execution. On a motion for summary judgment, the
    district court was required to construe the evidence in the light most favorable to
    Bucklew. Under that standard, without undisputed evidence from the State that it
    would alter its ordinary procedures, the court did not err by concluding that a finder
    of fact could infer that the State would proceed as in all other executions, with
    Bucklew lying on his back.5
    The State argues that the district court erred in discerning a genuine dispute of
    material fact on the first element because Dr. Zivot did not specify the length of the
    expected “twilight stage” during which Bucklew would be unable to adjust his
    positioning yet still sense pain. The State also complains that Dr. Zivot did not
    specify that Bucklew’s pain awareness would continue for fifty-two seconds or longer
    until brain waves ceased. There certainly are grounds to attack the reliability and
    credibility of Dr. Zivot’s opinion, including the imprecision of some of his testimony,
    his opposition to all forms of lethal injection, his possible misreading of the horse
    study on which he partially relied, and his inaccurate predictions of calamities at prior
    executions. But he did opine that Bucklew was likely to “experience prolonged
    feelings of suffocation and excruciating pain” if executed by lethal injection, R. Doc.
    182-1, at 147, and that there “will be points” before Bucklew dies when his ability to
    regulate his airway will be impaired so that he “will experience it as choking.” 
    Id. at 5
            Bucklew alleged in Paragraph 128 of his complaint that the State had offered
    to adjust the gurney so that Bucklew is not lying completely prone, but then
    continued as follows immediately thereafter: “Although the stated intent was to
    reduce the choking risk to Mr. Bucklew, the DOC has obtained no imaging studies
    of Mr. Bucklew since 2010, and therefore has no information on which to base any
    decisions about the angle of the gurney.” R. Doc. 53, at 43-44. The district court
    noted the State’s suggestion “that the execution could be performed with [Bucklew]
    in a different position,” but explained that “there is no evidence whether this has an
    effect on the procedure as a whole,” and concluded that the State had “not provided
    the Court with a basis for granting summary judgment based on the possibility of
    performing the execution with [Bucklew] in a sitting (or other) position.”
    -19-
    81. The district court did not err in concluding that it could not resolve the dispute
    between the experts on summary judgment.
    On the second element of Bucklew’s claim, the district court concluded as a
    matter of law that Bucklew failed to show that his proposed alternative method of
    execution—administration of nitrogen gas—would significantly reduce the
    substantial risk of severe pain that the court recognized under the first element. The
    majority affirms the district court’s judgment on this basis. Taking the evidence in
    the light most favorable to Bucklew, however, a factfinder could conclude that
    nitrogen gas would render Bucklew insensate more quickly than pentobarbital and
    would thus eliminate the risk that he would experience prolonged feelings of choking
    or suffocation. Dr. Antognini testified that a person who is administered nitrogen gas
    “would be unconscious very quickly,” and that the onset of action from lethal gas “is
    going to be relatively fast, just like Pentobarbital’s onset.” R. Doc. 182-5, at 58-59
    (emphasis added). Given Dr. Antognini’s testimony that pentobarbital would render
    Bucklew insensate within twenty to thirty seconds, the record in the light most
    favorable to Bucklew supports a finding based on Antognini’s testimony that nitrogen
    gas would relieve Bucklew from any pain of choking or suffocating within twenty to
    thirty seconds. A trier of fact may accept all, some, or none of a witness’s testimony,
    United States v. Candie, 
    974 F.2d 61
    , 65 (8th Cir. 1992), and a plaintiff may rely on
    testimony from the defendant’s expert to meet his burden if the testimony is
    advantageous to the plaintiff. See IBEW Local 98 Pension Fund v. Best Buy Co., Inc.,
    
    818 F.3d 775
    , 782 (8th Cir. 2016). If the factfinder accepted Dr. Zivot’s testimony
    as to the effect of pentobarbital, and Dr. Antognini’s uncontroverted testimony as to
    effect of nitrogen gas, then Bucklew’s proposed alternative method would
    significantly reduce the substantial risk of severe pain that the district court identified
    in its analysis of the first element.
    For these reasons, there are genuine disputes of material fact that preclude
    summary judgment and require findings of fact by the district court. I would
    -20-
    therefore remand the case for further proceedings. The district court may then
    promptly make appropriate factual findings about, among other things, how Bucklew
    will be positioned during an execution, whether his airway will be blocked during an
    execution, and how pentobarbital (and, if necessary, nitrogen gas) will affect his
    consciousness and ability to sense potential pain.
    *       *       *
    The State contends that we should not reach the merits of Bucklew’s claim
    because several procedural obstacles require dismissal of his complaint. The majority
    does not rely on these points, and I find them unavailing.
    First, the State contends that Bucklew did not raise his present claim in his
    fourth amended complaint. Bucklew’s complaint, however, does allege the essence
    of his current theory. The complaint asserts that the tumors in Bucklew’s throat
    require “him to sleep with his upper body elevated” because if he lies flat, “the tumor
    then fully obstructs his airway.” 
    Id. at 18-19.
    It continued: “Executions are
    conducted on a gurney, and the risks arising from Mr. Bucklew’s airway are even
    greater if he is lying flat. Because of the hemangiomas, Mr. Bucklew is unable to
    sleep in a normal recumbent position because the tumors cause greater obstruction in
    that position.” R. Doc. 53, at 35. Bucklew further alleged that execution by lethal
    injection “poses an enormous risk that Mr. Bucklew will suffer extreme, excruciating
    and prolonged pain – all accompanied by choking and struggling for air.” 
    Id. at 36.
    The complaint was adequate under a notice pleading regime to raise a claim that the
    execution procedure would result in an obstructed airway and choking or suffocation.
    If necessary, moreover, the district court acted within its discretion by treating
    the complaint as impliedly amended to include Bucklew’s present claim. See Fed. R.
    Civ. P. 15(b)(2). Bucklew clearly notified the State of his contention in his
    opposition to the State’s motion for summary judgment. R. Doc. 192-1, at 1-3, 11-17.
    -21-
    Yet rather than communicate surprise and object that the claim was not pleaded, the
    State addressed Bucklew’s contention on the merits. R. Doc. 200, at 4-5. Where a
    party has actual notice of an unpleaded issue and has been given an adequate
    opportunity to cure any surprise resulting from a change in the pleadings, there is
    implied consent to an amendment. Trip Mate, Inc. v. Stonebridge Cas. Ins. Co., 
    768 F.3d 779
    , 784-85 (8th Cir. 2014).
    Second, the State argues that the five-year statute of limitations bars Bucklew’s
    claim, because he was aware of his claim in 2008 and did not file his complaint until
    May 9, 2014. A claim under § 1983 accrues when a plaintiff has “a complete and
    present cause of action” and “can file suit and obtain relief.” Wallace v. Kato, 
    549 U.S. 384
    , 388 (2007) (quoting Bay Area Laundry & Dry Cleaning Pension Trust
    Fund v. Ferbar Corp. of Cal., 
    522 U.S. 192
    , 201 (1997)). Bucklew asserts that he did
    not have knowledge of his present claim, and therefore could not have filed suit and
    obtained relief, until his medical condition progressed and he was examined by Dr.
    Zivot in April 2014. As evidence that Bucklew could have brought his claim earlier,
    the State relies on a 2008 petition that Bucklew submitted to the Missouri Supreme
    Court. The petition sought funding for an expert witness to investigate the interaction
    of the State’s existing execution protocol with Bucklew’s health condition. The
    possible claim addressed in the 2008 funding petition, however, focused on the
    potential for uncontrolled bleeding and ineffective circulation of drugs within
    Bucklew’s body under the State’s former three-drug execution protocol. The petition
    does not demonstrate that Bucklew was then on notice of a claim that a future
    execution protocol using the single drug pentobarbital would create a substantial risk
    of severe pain resulting from tumors blocking his airway while laying supine during
    an execution.
    Third, the State urges that Bucklew’s claim is barred by res judicata or claim
    preclusion, because Bucklew could have litigated his as-applied challenge to the
    execution protocol in an earlier case styled Zink v. Lombardi, No. 12-04209-CV-C-
    -22-
    BP. In Zink, a group of inmates sentenced to death, including Bucklew, brought a
    facial challenge to Missouri’s execution protocol. A complaint was filed in August
    2012, and the eventual deadline for motions to amend pleadings was January 27,
    2014. Principles of claim preclusion do not bar Bucklew’s as-applied challenge if he
    was unaware of the basis for the claim in time to include it in the Zink litigation. See
    Whole Woman’s Health v. Hellerstedt, 
    136 S. Ct. 2292
    , 2305 (2016). The State again
    points to Bucklew’s 2008 funding petition in support of its preclusion defense, but
    for reasons discussed, that petition does not establish that Bucklew’s present claim
    was available to him in 2008. At oral argument, the State argued that Bucklew could
    have added his as-applied challenge to the Zink litigation after he was examined by
    Dr. Zivot in April 2014, because the district court granted the Zink plaintiffs leave to
    amend their complaint in May 2014. But the court’s order allowed the Zink plaintiffs
    leave to amend only a single count of the complaint to allege a feasible alternative
    method of execution. The order did not reopen the pleadings deadline for as-applied
    claims by the several individual plaintiffs. See Zink v. Lombardi, No. 12-04209-CV-
    C-BP, 
    2014 WL 11309998
    , at *4-5, 12 (W.D. Mo. May 2, 2014). The State therefore
    has not established that Bucklew’s as-applied claim is barred by res judicata.
    *       *       *
    For these reasons, I would reverse the judgment of the district court and
    remand for further proceedings to be conducted with dispatch.
