PER CURIAM.
       William Thompson appeals the district court’s1 dismissal of his 42 U.S.C. § 1983
complaint after an evidentiary hearing. Upon careful review of the record and the
parties’ briefs, we conclude the district court did not err in dismissing Thompson’s
equal protection claims because he did not show that defendants failed to treat similarly
situated persons in a like manner. We also conclude the district court did not err in
dismissing Thompson’s Eighth Amendment claim because he did not show that
defendants knowingly caused him to work beyond his medical classification, or that the
work resulted in any injury. Finally, the court did not abuse its discretion in denying
Thompson’s request for a second witness after determining that the witness’s testimony
would be cumulative. Accordingly, we affirm the judgment of the district court. See
8th Cir. R. 47B.
