PER CURIAM.

      Gregory Edwards, Jr., an Arkansas inmate, appeals the district court’s2
dismissal of his 42 U.S.C. § 1983 complaint following an evidentiary hearing. We
affirm.

      Edwards argues that the appellees failed to provide adequate security within his
barracks and failed to protect him from an attack by another inmate, in violation of the
Eighth Amendment’s prohibition against cruel and unusual punishment. At the
evidentiary hearing, Edwards was permitted to introduce evidence and testify.
Edwards testified that the attack by another inmate occurred when no guards were
watching his barracks and that the incident caused him serious medical problems,
including a laceration to his liver and kidney and skull fractures. The magistrate judge
denied Edwards’s request to hear testimony from the prison guards to elicit
information on their whereabouts during the attack.

      We have previously approved the use of evidentiary hearings to determine
whether the plaintiff has set forth a cognizable claim that should go to a jury or
whether the facts are so one-sided as to warrant a decision as a matter of law. Johnson
v. Bi-State Justice Ctr., 

, 135-36 (8th Cir. 1993) (indicating that the
standard is whether the plaintiff’s case would survive a Fed. R. Civ. P. 50(a) motion).
In such a hearing, the plaintiff’s testimony and evidence must be taken as true, all

      The Honorable David S. Doty, United States District Judge for the District of
Minnesota, sitting by designation.

        The Honorable James M. Moody, United States District Judge for the Eastern
District of Arkansas, adopting the report and recommendations of the Honorable H.
David Young, United States Magistrate Judge for the Eastern District of Arkansas.

appropriate inferences must be drawn in the plaintiff’s favor, and the judge may not
make any credibility determinations. 

       For Edwards to prevail, he must show that the lack of supervision of his
barracks posed a substantial risk of serious harm and that the appellees were
deliberately indifferent to that risk. See Lenz v. Wade, 

, 995 (8th Cir.
2007) (citing Farmer v. Brennan, 

, 834 (1994)). During the evidentiary
hearing, the magistrate judge accepted Edwards’s testimony as truthful and drew all
appropriate inferences in Edwards’s favor. Thereafter, the magistrate judge concluded
that, although Edwards was attacked by another inmate and suffered medical
consequences that were both severe and ongoing, he failed to present any evidence
that the appellees knew of a serious risk of harm or that they were deliberately
indifferent to that risk. Edwards acknowledged that he had not informed anyone at
the facility of his concerns of lack of supervision before the attack. He also
acknowledged that he had not been concerned that the inmate who attacked him posed
a risk of serious harm.

       The magistrate judge did not err in denying Edwards’s request to question the
appellees during the evidentiary hearing because such testimony would not have
constituted evidence different from or in addition to that which could be inferred from
Edwards’s testimony. See Munson v. Norris, 

, 880 (8th Cir. 2006) (“For
purposes of the evidentiary hearing, all of [the plaintiff’s] testimony had to be (and
was) regarded as true, making other witnesses’ testimony cumulative.” (internal
citation omitted)). Even after taking Edwards’s testimony as true and drawing all
inferences in his favor, the fact that Edwards was violently attacked is not enough to
establish a trial-worthy issue of fact on whether the appellees were deliberately
indifferent to a serious risk of harm.

      The judgment is affirmed.
