Barry Turner, an Arkansas inmate, appeals the district court’s 1 adverse grant of summary judgment in his 42 U.S.C. § 1983 action claiming defendants failed to protect him from an assault by another inmate. We conclude that the court properly vacated an earlier order granting default judgment against some of the defendants, see Fed.R.Civ.P. 54(b), and that summary judgment was warranted because Mr. Turner did not show he faced a substantial risk of serious harm which defendants knew of and disregarded, see Farmer v. Brennan, 511 U.S. 825, 834, 837, 114 S.Ct. 1970, 128 L.Ed.2d 811 (1994); Prater v. Dahm, 89 F.3d 538, 541 (8th Cir. 1996) (noting it is well settled that Eighth Amendment imposes duty on part of prison officials to protect prisoners from attacks; duty to protect inmate requires only that prison officials take reasonable measures to abate substantial risks of serious harm of which they are aware).

Accordingly, w'e affirm the judgment of the district court.
