    we find no reversible error and affirm the judgment of the district court.1
    1
    The Honorable John A. Ross, United States District Judge for the Eastern
    District of Missouri.
    I. Background
    In 2012, the Drug Enforcement Administration (DEA) began an investigation
    into the suspected drug trafficking activities of Jeremy Poe. After Poe was arrested
    in January 2013 in possession of a kilogram of cocaine, he agreed to cooperate with
    the DEA and assist them in their investigation. At a meeting with the DEA on
    January 14, 2013, Poe told the DEA that he had received the kilogram of cocaine
    from David Frazier, and that he believed that Frazier had gotten the cocaine from
    Torrance Cotton. Following that meeting, Poe agreed to meet with Frazier and
    arrange further drug transactions while wearing a wire. Poe had two separate
    meetings with Frazier on January 17, first at Chilimacks, a courier service where
    Frazier and Cotton worked, and second at Frazier’s residence. Poe met again with
    Frazier on January 18. Following that meeting, the DEA arrested Frazier and seized
    one kilogram of cocaine from a safe in his residence.
    As a result of this investigation, Torrance Cotton was indicted on May 1, 2013,
    and charged with one count of conspiracy to distribute cocaine and one count of
    possession with intent to distribute cocaine. Cotton was convicted of both counts
    following a jury trial on April 3, 2014. On appeal, Cotton contests the admission of
    evidence of his prior convictions, admission of a statement made by David Frazier
    after his arrest, and denial of his motion for a new trial based on a Brady violation.
    II. Discussion
    A. Admission of Evidence of Prior Convictions
    Cotton asserts that the district court improperly allowed the government to
    introduce evidence of his prior convictions for possession of cocaine with intent to
    distribute and attempted drug trafficking. Because Cotton did not make a
    contemporaneous objection to the introduction of this evidence, our review is for
    -2-
    plain error unless the district court made a final and definitive pretrial ruling on the
    admissibility of this evidence. United States v. Young, 
    753 F.3d 757
    , 775 (8th Cir.
    2014). The admissibility of the evidence was addressed at two pretrial conferences,
    on November 26, 2013, and January 23, 2014. At both pretrial conferences, the
    district court made a provisional, non-definitive ruling that the evidence was
    admissible, specifically anticipating a contemporaneous objection at trial. However,
    before voir dire began on March 31, 2014, the district court again addressed the
    admissibility of the evidence of Cotton’s prior convictions, stating “I do think that
    there is still a basis to introduce this 404(b) evidence. . . . So the objection will be
    overruled. I will, as I say, before that evidence is sought to be introduced, want to see
    a limiting instruction.” This March 31 ruling was, by its terms, final, definitive, and
    non-provisional. Cf. 
    id. (“when the
    district court reserves its ruling or otherwise
    indicates that the ruling is provisional, then the proponent should reintroduce the
    court to the issue at the appropriate time”) (emphasis added). The court stated that
    the objection “will be overruled,” and referred to an anticipated limiting instruction
    with regard to the evidence that would be admitted. At this point, the court’s ruling
    on the admissibility of the evidence was clear, and counsel would no longer have had
    any reason to doubt whether that ruling was definitive. See id.; Fed. R. Evid. 103(b)
    & advisory committee’s note to 2000 amendment. We therefore conclude that Cotton
    properly preserved this claim of error, and accordingly review the district court’s
    decision to admit the evidence of Cotton’s prior convictions for abuse of discretion.
    
    Young, 753 F.3d at 767
    .
    Evidence of a defendant’s prior convictions is categorically inadmissible to
    prove the defendant’s criminal propensity. Fed. R. Evid. 404(b)(1). Evidence of
    prior convictions may, however, be admissible to prove a specific element or aspect
    of the charged offense, such as “motive, opportunity, intent, preparation, plan,
    knowledge, identity, absence of mistake, or lack of accident.” Fed. R. Evid.
    404(b)(2). Where there is a proper purpose for evidence of a prior conviction, the
    conviction may be admitted if it is “(1) relevant to a material issue; (2) similar in kind
    -3-
    and not overly remote in time to the crime charged; (3) supported by sufficient
    evidence; and (4) higher in probative value than prejudicial effect.” United States v.
    Trogdon, 
    575 F.3d 762
    , 766 (8th Cir. 2009) (quoting United States v. Williams, 
    534 F.3d 980
    , 984 (8th Cir. 2008)). This is considered a rule of inclusion, meaning that
    if these elements of admissibility are satisfied, the evidence will be excluded only
    when it is offered solely to prove criminal propensity. United States v. Foster, 
    344 F.3d 799
    , 801 (8th Cir. 2003).
    Federal Rule of Evidence 404(b)(2) identifies the purposes for which evidence
    of prior convictions may be admitted, but merely reciting those permissible purposes
    without more is not sufficient to render evidence of a prior conviction admissible in
    any particular case. Rather, when the defendant raises a timely objection to
    admission of the evidence, Rule 404(b) requires a careful inquiry and analysis of the
    purpose for which the evidence is offered. The government—as proponent of the
    evidence—must identify the permissible non-propensity purpose for the evidence,
    and must articulate the relationship between the prior conviction and a material issue
    in the case. If the district court, upon consideration of the facts of the case, the
    elements of proof required, and the circumstances of the prior conviction, concludes
    that a permissible non-propensity purpose exists for the evidence, the court must then
    consider whether the other requirements for admissibility are satisfied. See United
    States v. Armstrong, 
    782 F.3d 1028
    , 1034 (8th Cir. 2015) (holding that even if
    introduced for a proper purpose, to be admissible, prior bad act evidence must be
    relevant, supported by sufficient evidence, similar in kind and close in time to the
    crime charged, and higher in probative value than prejudicial effect). If, however, the
    court concludes that the only purpose for the evidence is to show the defendant’s
    criminal propensity, Rule 404(b)(1) prohibits its admission.
    Here, there is reason to be concerned that the evidence was not properly
    admitted under Rule 404(b). Following Cotton’s pretrial objection to the evidence,
    the government generally asserted that Cotton’s prior convictions were admissible to
    -4-
    prove “knowledge, intent, and motive.”2 The district court made a similarly general
    preliminary ruling, stating that the convictions were relevant to prove “lack of
    mistake, knowledge, identity, those issues for which 404(b) evidence is used.” Thus,
    though both the government and the district court correctly recited some of the
    purposes for which evidence of prior convictions may be used, the court did not
    analyze the purpose for which the evidence was being offered in this case. Mere
    recitation of the Rule without an accompanying case-specific analysis risks couching
    criminal propensity in terms of knowledge, intent, or lack of mistake. Rule 404(b),
    by its own terms, requires more.
    Nevertheless, under the particular circumstances of this case, any error in
    admitting the evidence of Cotton’s prior convictions was harmless. An evidentiary
    error is harmless if it did not substantially influence the jury’s verdict. United States
    v. Aldridge, 
    664 F.3d 705
    , 714 (8th Cir. 2011). Error may be harmless where “the
    government introduced ample competent evidence from which the jury could
    conclude beyond a reasonable doubt that the defendant was guilty even without the
    evidence that should have been excluded.” 
    Id. (quoting United
    States v. Falls, 
    117 F.3d 1075
    , 1077 (8th Cir. 1997)). Here, the evidence against Cotton included: the
    2
    On appeal, the government also asserts that evidence of the convictions was
    admissible to prove lack of mistake or accident. This argument is based on Cotton’s
    assertion at trial that his fingerprints appeared on a plastic shopping bag wrapped
    around the cocaine by happenstance. However, Cotton’s argument was not that he
    had accidentally touched the bag wrapping the cocaine, but that he had touched the
    bag in the ordinary course of business at his workplace before the bag was involved
    in the drug packaging. The government’s argument that the prior convictions are
    relevant as to mistake or accident therefore ultimately amounts to an argument that
    a person with prior drug convictions must have been involved with a drug transaction
    when he touched the plastic bag, which is, of course, a non-permissible propensity-
    based use of the evidence. We further note that the government did not raise this
    argument to the district court before trial in support of the admissibility of the
    evidence; rather, the argument of lack of mistake or accident arose only in closing
    argument.
    -5-
    testimony of Jeremy Poe, including David Frazier’s statements to Poe that Cotton was
    his cocaine supplier; recorded conversations from January 17, 2013, in which Frazier
    referred to “T” and “Torrance”; testimony from the DEA agents that Cotton arrived
    at Chilimacks on January 18, 2013, with a package under his arm; and Cotton’s
    fingerprints on the outside wrapping of the cocaine found in Frazier’s safe. This
    evidence, if given credence by the jury, is “sufficiently strong for us to conclude that
    the conviction[s], even if improperly admitted, did not have ‘a substantial influence
    on the jury’s verdict.’” United States v. Donnell, 
    596 F.3d 913
    , 921 (8th Cir. 2010)
    (quoting United States v. Lupino, 
    301 F.3d 642
    , 645 (8th Cir. 2002)). Furthermore,
    the district court gave an appropriate limiting instruction stating that the evidence of
    Cotton’s prior convictions “[was] not evidence that he committed such acts in this
    case,” and could only be used “to help [] decide knowledge, intent, and absence of
    mistake or accident.” The presence of a limiting instruction “diminishes the danger
    of any unfair prejudice arising from the admission of other acts.” 
    Aldridge, 664 F.3d at 715
    (quoting United States v. Strong, 
    415 F.3d 902
    , 906 (8th Cir. 2005)).
    We do not underestimate the impact evidence of a prior conviction can have
    on a jury’s assessment of a criminal case. The Federal Rules of Evidence limit the
    use of evidence of prior convictions for good reason. Fed. R. Evid. 404(b), 403. But
    here, given the testimony and physical evidence directly linking Cotton to the
    distribution of cocaine, Cotton is unable to show that introduction of the evidence of
    prior convictions had a substantial influence on the jury’s verdict. 
    Aldridge, 664 F.3d at 714
    . Accordingly, any error associated with the admission of the evidence is not
    grounds for reversal.
    B. Introduction of David Frazier’s Post-Arrest Statement
    At Cotton’s trial, co-conspirator David Frazier did not testify but Jeremy Poe
    did. The government presented Frazier’s co-conspirator statements through Poe’s
    testimony. Cotton sought to impeach Frazier by introducing a portion of an affidavit
    -6-
    written and attested by Frazier in July 2013, months after Frazier’s arrest. The
    impeachment evidence was initially limited to the following statement in Frazier’s
    affidavit: “I never had any drug involvement with Mr. Cotton at all . . . .” The
    government then attempted to rehabilitate Frazier by calling the police officer who
    interviewed Frazier after he was arrested on January 18, 2013. The officer testified
    to Frazier’s statement following his arrest, which—consistent with Frazier’s co-
    conspirator statements introduced through Poe’s testimony—implicated Cotton as
    Frazier’s source of cocaine. On sur-impeachment, Cotton introduced the remainder
    of Frazier’s affidavit, in which Frazier explained that he made the post-arrest
    statement to police on January 18 only “so [he] could get away from them” and
    apologized for “involv[ing] Mr. Cotton in this situation at all.” The district court
    allowed the introduction of Frazier’s co-conspirator statements pursuant to Federal
    Rule of Evidence 801(d)(2)(E), and allowed the introduction of the subsequent
    impeachment and rehabilitative evidence pursuant to Federal Rule of Evidence 806.
    Cotton now asserts that the district court erred in allowing the government to
    introduce Frazier’s post-arrest statement to rehabilitate the credibility of Frazier’s co-
    conspirator statements.
    Cotton first argues that admission of Frazier’s post-arrest statement violated
    his rights under the Confrontation Clause. Because the statement was offered for
    impeachment and not to prove the truth of the matter asserted, there was no
    Confrontation Clause violation in this case. See United States v. Rodriguez, 
    484 F.3d 1006
    , 1013–14 (8th Cir. 2007); United States v. Kehoe, 
    310 F.3d 579
    , 591 (8th Cir.
    2002).
    Cotton next argues that Frazier’s statement was inadmissible under the Rules
    of Evidence. We begin by analyzing the admissibility of each piece of evidence
    offered in the relevant series. First, David Frazier’s co-conspirator statements were
    undisputedly admissible as non-hearsay co-conspirator statements pursuant to Rules
    402 and 801(d)(2)(E). Fed. R. Evid. 402 (in general, relevant evidence is admissible);
    -7-
    Fed. R. Evid. 801(d)(2)(E) (statements made by co-conspirators during and in
    furtherance of the conspiracy are not hearsay). The parties also agree that the limited
    portion of Frazier’s affidavit (“I never had any drug involvement with Mr. Cotton at
    all”) was properly admitted as impeachment evidence pursuant to Rule 806. Fed. R.
    Evid. 806 (when a co-conspirator statement is admitted pursuant to Rule
    801(d)(2)(E), “the declarant’s credibility may be attacked, and then supported, by any
    evidence that would be admissible for those purposes if the declarant had testified as
    a witness. . . . The court may admit evidence of the declarant’s inconsistent statement
    or conduct, regardless of when it occurred or whether the declarant had an
    opportunity to explain or deny it”). The propriety of admitting these first two pieces
    of evidence is not in controversy.
    What is at issue is whether Frazier’s post-arrest statement was admissible as
    rehabilitation evidence. Cotton argues that the only Rule of Evidence that could
    support admission of Frazier’s post-arrest statement is Rule 801(d)(1)(B). But the
    district court did not admit the post-arrest statement under this rule, and neither the
    government nor Cotton raised the application of this rule to Frazier’s post-arrest
    statement at trial. Rule 801(d)(1)(B), in relevant part, provides that a prior statement3
    3
    The parties spend a substantial amount of time disputing whether the fact that
    Frazier’s post-arrest statement did not actually predate the statements presented as
    substantive evidence at trial affects the admissibility of the statement. However, the
    requirement that the prior consistent statement predate the alleged motive to fabricate
    is a protection premised at least in part on the assumption that the prior consistent
    statement may be admitted as substantive evidence. Tome v. United States, 
    513 U.S. 150
    , 157–58 (1995). Moreover, the Advisory Committee Notes to Rule 806
    recognize the paradox created when a declarant is subject to impeachment by use of
    an inconsistent statement, noting that in cases where the declarant is not a live
    witness, “the inconsistent statement may well be a subsequent one.” Fed. R. Evid.
    806 advisory committee’s note to 1972 proposed rules. In that circumstance, “[t]he
    writers favor allowing the subsequent statement.” However, the note only directly
    addresses the use of prior inconsistent statements.
    -8-
    consistent with a declarant’s testimony is not hearsay if the statement is offered to
    rebut an accusation that the declarant fabricated his testimony4 or acted under an
    improper influence in testifying. Frazier’s post-arrest statement was not offered as
    non-hearsay substantive evidence. Rather, the government offered it solely to
    rehabilitate Frazier after his testimony had been impeached by the introduction of an
    inconsistent statement, and the jury received a limiting instruction to that effect. On
    its face, therefore, Rule 801(d)(1)(B) does not apply to Frazier’s post-arrest statement.
    Instead, the district court admitted the post-arrest statements “under Rule 806
    for the limited purpose of supporting the credibility of the declarant [Frazier], whose
    credibility has been attacked by the defendant.” Pursuant to Rule 806, Frazier’s
    credibility was “attacked, and [could] then [be] supported, by any evidence that would
    be admissible for those purposes if [he] had testified as a witness.” Fed. R. Evid.
    806.5
    4
    The parties also make much of Frazier’s motive to fabricate, each arguing that
    Frazier had a motive to fabricate different statements for different reasons. However,
    the parties did not make these arguments at trial, and the district court therefore had
    no opportunity to make a finding as to whether there was in fact “an express or
    implied charge” of recent fabrication. Fed. R. Evid. 801(d)(1)(B)(i); see United
    States v. Hoover, 
    543 F.3d 448
    , 453 (8th Cir. 2008). That the parties cannot agree on
    what motive to fabricate is in dispute highlights the importance of raising these issues
    to the district court, rather than waiting to do so on appeal.
    5
    Cotton argues that the post-arrest statement is inadmissible under Rule
    801(d)(1)(B), but he offers no other argument for why it is inadmissible as
    rehabilitative evidence pursuant to Rule 806. Despite the lack of clarity in his
    argument, the nature of his challenge to the admissibility of the rehabilitative
    evidence is essentially clear, and we therefore consider whether the evidence was
    properly admitted under the applicable rule.
    -9-
    Use of a prior consistent statement to rehabilitate the credibility of a witness
    who has been impeached by a prior inconsistent statement is appropriate when the
    statement contextualizes, clarifies, or amplifies the meaning of the witness’s
    testimony or inconsistent statement. See 
    Hoover, 543 F.3d at 453
    ; United States v.
    Kenyon, 
    397 F.3d 1071
    , 1081 (8th Cir. 2005). For example, a prior consistent
    statement may be admissible to explain to the jury why a seemingly inconsistent prior
    statement elicited on cross-examination was not in fact inconsistent at all. See
    
    Hoover, 543 F.3d at 454
    . However, “it is not proper to admit ‘all prior consistent
    statements simply to bolster the credibility of a witness who has been impeached by
    particulars.’” United States v. Ramos-Caraballo, 
    375 F.3d 797
    , 803 (8th Cir. 2004)
    (quoting United States v. Simonelli, 
    237 F.3d 19
    , 28 (1st Cir. 2001)). In other words,
    prior consistent statements are not admissible as rehabilitative evidence to the extent
    that they are merely cumulative of the testimony already presented; but they may be
    admissible to the extent that they explain either the testimony or the impeaching
    inconsistent statement, and therefore allow the jury to better assess the substantive
    evidence presented.
    Whether a witness may be properly rehabilitated by the introduction of a prior
    consistent statement is a fact-based inquiry, and the decision to admit or exclude such
    evidence is left to the sound discretion of the district court. 
    Kenyon, 397 F.3d at 1081
    . The government did not assert that Frazier’s affidavit (the impeaching
    inconsistent statement) or co-conspirator testimony was misunderstood or taken out
    of context, such that a prior consistent statement might have explained or clarified
    either for the benefit of the jury. Yet, for reasons particular to this case, it would be
    difficult to conclude that the district court abused its discretion in admitting the post-
    arrest statement. The primary reason is that on sur-impeachment, Cotton was
    permitted to introduce the entirety of Frazier’s affidavit, which included both the
    impeaching inconsistent statement and an explanation of why he had not been truthful
    in his post-arrest statement. The jury therefore had before it 1) Frazier’s substantive
    -10-
    testimony, introduced as co-conspirator statements through Poe; 2) the impeaching
    inconsistent statement in Frazier’s affidavit; 3) Frazier’s January 18 statement to
    police, which was consistent with the substantive testimony; and 4) Frazier’s
    explanation of his January 18 statement, contained in the balance of his affidavit.
    Though this is an unusual pattern for the introduction of such evidence, the basic
    outcome was that the jury was able to consider the substantive evidence, as well as
    the context of prior consistent and inconsistent statements that bore on the truth of
    that evidence. The district court gave a limiting instruction—to which neither party
    objected—before the evidence was admitted, instructing the jury on the limited
    purposes for which it could consider the evidence. Moreover, when the government
    was presenting the post-arrest statement via the testimony of the arresting agent, the
    district court sua sponte raised the concern that certain questions went beyond the
    proper scope of the testimony, and sustained Cotton’s objection on that ground. The
    district court’s careful attention to the admission of the rehabilitation evidence
    presented supports the conclusion that the court did not abuse its discretion in
    admitting all of the proffered evidence for both parties regarding the credibility of
    Frazier’s co-conspirator statements.
    We also note that Cotton was permitted to introduce all the evidence he sought
    to introduce on this issue. Only because the post-arrest statement was admitted was
    Cotton allowed to introduce Frazier’s full affidavit, which ostensibly exculpated
    Cotton of any drug-related involvement with Frazier. Furthermore, Frazier’s post-
    arrest statement was not substantively different or significantly more harmful than the
    statements originally admitted through Poe’s testimony as co-conspirator statements,
    making it unlikely that the statement had any prejudicial effect. Cf. 
    Kenyon, 397 F.3d at 1082
    . Under these somewhat complex and unusual circumstances, the district
    court did not abuse its discretion in allowing the post-arrest statement to be admitted.
    -11-
    C. Brady Evidence
    After Jeremy Poe was arrested on January 14, 2013, he identified Cotton in a
    photograph shown to him by DEA agents. At trial, the government introduced a
    photograph of Cotton into evidence as Government’s Exhibit 1. Several government
    witnesses, including Poe, were shown Exhibit 1 and identified it as the photograph
    that had been shown to Poe in order to identify Cotton in January 2013. However,
    the photograph shown at trial (Exhibit 1) had been taken on November 1, 2013.
    Cotton asserts that the government suppressed the earlier photograph—the one
    actually shown to Poe in January 2013—in violation of his Brady rights.
    A Brady violation occurs when the government suppresses evidence that is
    favorable to a defendant and is material as to either guilt or punishment. Brady v.
    Maryland, 
    373 U.S. 83
    , 87 (1963). For evidence to be material as to guilt, there must
    be a reasonable probability that the result of the proceeding would have been different
    had the evidence been disclosed. Youngblood v. West Virginia, 
    547 U.S. 867
    , 870
    (2006) (per curiam). Here, the district court concluded that there was no Brady
    violation because
    the evidence was not material. Poe’s identification of Defendant Cotton
    was not central to the evidence in this case . . . . Moreover, the case
    agents and Poe were fully cross-examined and impeached at trial on the
    issue of Government Exhibit 1. At most, this evidence would be
    cumulative impeachment evidence.
    We agree with the district court. There is no reasonable probability that the
    result of the proceeding would have been different had the earlier photograph been
    disclosed to Cotton. Accordingly, there was no Brady violation associated with the
    government’s failure to disclose the photograph, and the district court did not abuse
    its discretion in denying Cotton’s motion for a new trial.

    III. Conclusion
    For the foregoing reasons, we affirm the judgment of the district court.
    COLLOTON, Circuit Judge, concurring in part and concurring in the judgment.
    I concur in all but Parts II.A and III of the court’s opinion. In my view, the
    district court did not abuse its discretion in admitting evidence of Torrance Cotton’s
    prior convictions, and I do not join the court’s dicta concerning the application of
    Federal Rule of Evidence 404(b).
    Rule 404(b) provides that evidence of a crime, such as a prior conviction, may
    be admissible for several enumerated purposes. Cotton had sustained prior
    convictions for possession with intent to distribute cocaine and attempted trafficking
    in drugs. The district court ruled that these prior convictions were admissible to
    prove “knowledge, intent, and absence of mistake or accident.” These are among the
    purposes enumerated in the rule. The district court explained that Rule 404(b) “is a
    rule of inclusion,” that there was “sufficient temporal proximity” to admit the prior
    convictions, that the prior convictions were “particularly relevant, because the drug
    involved is cocaine,” and that the court would give “a limiting instruction to the jury
    to try to limit any prejudice that there might be, because it is important to balance the
    probative value with the prejudice.” R. Doc. 713, at 24-25.
    In this case, Cotton was charged with conspiracy to distribute cocaine and
    possession with intent to distribute cocaine. The conspiracy charge required proof
    that Cotton voluntarily and intentionally joined an agreement, and that he knew the
    purpose of the agreement. On the substantive count, the government was required to
    prove that Cotton knew that what he possessed was cocaine, as opposed to some other
    -13-
    substance, and that he intended to distribute the cocaine, rather than use it, store it,
    or otherwise dispose of it. Cotton’s prior convictions were relevant on the issues of
    knowledge or intent. It was more probable with the evidence of prior convictions
    than without it, for example, that Cotton knew the substance he possessed was
    cocaine and that he intended to distribute it. See United States v. Crowder, 
    141 F.3d 1202
    , 1209 (D.C. Cir. 1998) (en banc). The evidence of prior convictions likewise
    made it more probable that Cotton knew that he joined a conspiracy to distribute
    cocaine and did not participate unwittingly. United States v. Robinson, 
    809 F.3d 991
    ,
    997-98 (8th Cir. 2016); United States v. Brown, 
    956 F.2d 782
    , 787 (8th Cir. 1992).
    In a drug trafficking prosecution, evidence of a prior drug conviction is nearly
    always relevant to show a defendant’s knowledge or intent in committing the charged
    offense. See, e.g., United States v. Armstrong, 
    782 F.3d 1028
    , 1034 (8th Cir. 2015);
    United States v. Horton, 
    756 F.3d 569
    , 579-80 (8th Cir. 2014); United States v.
    Gipson, 
    446 F.3d 828
    , 831 (8th Cir. 2006); United States v. Frazier, 
    280 F.3d 835
    ,
    847 (8th Cir. 2002); United States v. Williams, 
    895 F.2d 1202
    , 1205 (8th Cir. 1990).
    Admission of prior convictions to prove absence of mistake in a drug case is perhaps
    less common, but it is also supported by circuit precedent. United States v. Ellis, No.
    15-2243, 
    2016 WL 1077131
    , at *7 (8th Cir. Mar. 18, 2016) (“Ellis’s prior conviction
    was for delivering heroin—the very drug he was charged with distributing in this
    case, which made the prior conviction particularly relevant to knowledge, intent, and
    absence of mistake.”); United States v. McGilberry, 
    620 F.3d 880
    , 886-87 (8th Cir.
    2010); United States v. Shoffner, 
    71 F.3d 1429
    , 1432 (8th Cir. 1995) (“Shoffner’s
    prior involvement in marijuana dealing also tends to prove motive, knowledge, and
    absence of mistake to rebut Shoffner’s claim that he was merely present and unaware
    of the conspiracy.”). The district court here gave a cautionary instruction to the jury,
    explaining the limited purposes for which the evidence of prior convictions was
    received. This instruction “diminishe[d] the danger of any unfair prejudice arising
    from the admission of other acts.” United States v. Franklin, 
    250 F.3d 653
    , 659 (8th
    -14-
    Cir. 2001). The district court did not abuse its discretion in concluding that the
    probative value was not substantially outweighed by a danger of unfair prejudice. See
    Fed. R. Evid. 403; Ellis, 
    2016 WL 1077131
    , at *7; United States v. Halk, 
    634 F.3d 482
    , 488 (8th Cir. 2011).
    The court does not conclude that there was error, but sees a “reason to be
    concerned,” because “Rule 404(b), by its own terms, requires more” explanation for
    admissibility than what the government and the district court provided. Ante, at 4-5.
    Not so. The terms of the rule speak only to the purposes for which evidence is
    admissible; they do not address what the prosecution or the district court must specify
    on the record. Our decisions encourage the government and the district court to
    articulate a theory of admissibility to facilitate appellate review, but even where the
    government simply reads a list of issues for which prior bad acts can be admitted
    under Rule 404(b), that “is not in itself a basis for reversal.” United States v.
    Mothershed, 
    859 F.2d 585
    , 589 (8th Cir. 1988). The reviewing court must examine
    the material issues from the trial and determine whether the evidence of prior
    convictions was relevant for the purposes specified. 
    Id. The evidence
    at issue here was clearly relevant to the limited issues on which
    it was admitted—knowledge, intent, and absence of mistake. We have said before
    in the context of Rule 404(b) that “[j]udges need not explain the obvious, even
    briefly.” United States v. Burk, 
    912 F.2d 225
    , 229 (8th Cir. 1990) (internal quotation
    marks omitted). As in Burk, “the prosecution made clear enough the purpose for
    which it wished to elicit the evidence,” and “further explanation from the court was
    unnecessary.” 
    Id. Likewise, “the
    factors upon which the probative value/prejudice
    evaluation were made are readily apparent from the record, and there is no substantial
    uncertainty about the correctness of the district court’s ruling.” 
    Id. (internal quotation
    marks omitted).

    The evidence of Cotton’s prior convictions was properly admitted. The district
    court may have erred by not sustaining Cotton’s objection to the government’s
    closing argument that the prior convictions tended to prove the absence of a “cosmic
    accident,” because the argument did not address a true “accident,” see ante, at 5 n.2,
    but I agree with the court that any error in that respect was harmless.
    For these reasons, I concur in the judgment.
