PER CURIAM.

       Missouri state prisoner Mark Harris appeals the district court’s1 dismissal of his
42 U.S.C. § 1983 claim against numerous prison officials. Harris alleged that prison
officials failed to follow prison disciplinary regulations in violation of his due process




      1
      The Honorable Fernando J. Gaitan, Jr., United States District Judge for the
Western District of Missouri.
rights and that his sentence in disciplinary segregation violated his Eighth Amendment
right to be free from cruel and unusual punishment.

       Having carefully reviewed the record, we note that defendants properly raised
a 42 U.S.C. § 1997e(a) lack-of-exhaustion affirmative defense, see Nerness v.
Johnson, 401 F.3d 874, 876 (8th Cir. 2005) (per curiam) (Prison Litigation Reform
Act’s exhaustion requirement is affirmative defense that defendant has burden to plead
and prove), and the record contains no indication that Harris exhausted prison
remedies as to his Eighth Amendment claim. See Kozohorsky v. Harmon, 332 F.3d
1141, 1143 (8th Cir. 2003) (when multiple prison-condition claims have been joined,
§ 1997e(a) requires that all available prison grievance remedies be exhausted as to all
claims).

       Accordingly, we affirm on the ground that Harris had failed to exhaust his
Eighth Amendment claim at the time of filing. See Johnson v. Jones, 340 F.3d 624,
627 (8th Cir. 2003) (if exhaustion is not completed at time of filing, dismissal is
mandatory). We also modify the dismissal to be without prejudice. See Calico Trailer
Mfg. Co. v. Ins. Co. of N. Am., 155 F.3d 976, 978 (1998) (affirming dismissal for
failure to exhaust administrative remedies, but modifying to be without prejudice).
