                                ____________
Before COLLOTON, GRUENDER, and STRAS, Circuit Judges.
                        ____________

PER CURIAM.

       Arkansas prisoner Michael Anderson appeals the district court’s pre-service
dismissal of his 42 U.S.C. § 1983 action, in which he alleged that he received prison
discipline in retaliation for filing a grievance, and in violation of his due process
rights. Following careful de novo review, see Cooper v. Schriro, 

, 783
(8th Cir. 1999) (per curiam) (holding that dismissal under 28 U.S.C. § 1915A for
failure to state a claim is reviewed de novo), we affirm in part and reverse in part.


       We conclude that the district court did not err in dismissing Anderson’s
retaliation claim, as the disciplinary report constituted “some evidence” upon which
the disciplinary violations were based. See Hartsfield v. Nichols, 

, 829-
31 (8th Cir. 2008) (holding that a retaliation claim fails if there is “some evidence”
that the inmate violated a prison rule; stating that a report from a correctional officer,
even if disputed by the inmate and supported by no other evidence, legally suffices
as “some evidence” upon which to base a prison disciplinary violation, if the
violation is found by an impartial decision-maker).


      We conclude, however, that the district court erred in dismissing Anderson’s
due process claims as barred by Heck v. Humphrey, 

, 486-87 (1994)
(holding that, to recover damages for an allegedly unconstitutional conviction or
imprisonment, or for other harm caused by actions whose unlawfulness would render
a conviction or sentence invalid, § 1983 plaintiff must prove that the conviction or
sentence has been invalidated). While Heck applies in cases where the prisoner’s
challenge to a prison disciplinary decision would threaten his underlying criminal
conviction or the duration of his sentence, Anderson did not state that he lost any
good-time credit as a result of his disciplinary convictions. See Edwards v. Balisok,


, 645-48 (1997) (extending Heck to prison disciplinary proceedings that
result in loss of good-time credits); Muhammad v. Close, 

, 751 (2004)
(per curiam) (holding that Heck’s requirement to resort to state litigation and federal
habeas before pursuing § 1983 action is not implicated by prisoner’s challenge to
disciplinary proceeding that threatens no consequence for his criminal conviction or
the duration of his sentence); Sheldon v. Hundley, 

, 234 (8th Cir. 1996)
(“[P]risoners who challenge disciplinary rulings that do not lengthen their sentence
are probably outside the habeas statute and able to seek damages under § 1983
without showing favorable termination in an authorized state tribunal or a federal
habeas court.”); cf. Robertson v. Kelley, No. 18-CV-00288, 

, at *3
(E.D. Ark. Feb. 20, 2020) (holding that Heck barred claim for monetary damages
where inmate lost over one year of good-time credit as a result of disciplinary
conviction), report and recommendation adopted, 

 (E.D. Ark.
March 5, 2020), summarily aff’d sub nom. Robertson v. Payne, No. 20-1621, 

 (8th Cir. July 29, 2020).


       We do not decide whether Anderson properly stated a due process claim. He
alleges that he did not receive fair notice of the specific allegations against him
because he was ordered to pay $10,989.83 in restitution despite not being charged
with destruction of property. See Wolff v. McDonnell, 

, 564 (1974). He
further alleges that he was not able to mount an adequate defense because he could
not call live witnesses at his disciplinary hearing. See Turner v. Caspari, 

, 391 (8th Cir. 1994) (“[P]rison officials may not arbitrarily deny an inmate’s
request to call witnesses.”). The district court never reached the merits of Anderson’s
due process claim. Accordingly, we remand for the district court to address the merits
of that claim in the first instance. See Iowa Right to Life Comm., Inc. v. Tooker, 

, 604 (8th Cir. 2013) (reversing dismissal and remanding for district court
to consider merits of constitutional claim in the first instance).
      Accordingly, we affirm in part, reverse in part, and remand the case for further
proceedings consistent with this opinion. We also vacate the district court’s
assessment of a strike under 28 U.S.C. § 1915(g).
