MEMORANDUM **

Calvin Rouse, a Washington state prisoner, appeals pro se from the district court’s summary judgment for defendants in his 42 U.S.C. § 1983 action alleging discriminatory placement in administrative segregation, deliberate indifference to serious medical needs, and excessive force. We have jurisdiction under 28 U.S.C. § 1291. We review de novo the district court’s summary judgment, Toguchi v. Chung, 391 F.3d 1051, 1056 (9th Cir. 2004), and for abuse of discretion its refusal to appoint counsel, Terrell v. Brewer, 935 F.2d 1015, 1017 (9th Cir. 1991), and we affirm.

The district court properly granted summary judgment for defendants on Rouse’s discrimination claim because Rouse offered no evidence that prison officials were motivated by discriminatory animus against Rouse on the basis of his race or religion when they placed him in administrative segregation. See Forsberg v. Pac. Northwest Bell Tel. Co., 840 F.2d 1409, 1419 (9th Cir. 1988) (“[Pjurely eonclusory allegations of alleged discrimination, with no concrete, relevant particulars, will not bar summary judgment.”).

The district court properly granted summary judgment for defendants on Rouse’s claim that they were deliberately indifferent to his skin infection, which Rouse concedes medical staff treated. See Toguchi, 391 F.3d at 1060 (“A showing of medical malpractice or negligence is insufficient to establish a constitutional deprivation under the Eighth Amendment.”).

The district court properly granted summary judgment for defendants on Rouse’s claim that they subjected him to excessive *792 force because Rouse failed to raise a triable issue as to whether correctional officers acted in a good-faith effort to restore order or maliciously and sadistically to cause harm. See Hudson v. McMillian, 503 U.S. 1, 6-7, 112 S.Ct. 995, 117 L.Ed.2d 156 (1992).

The district court did not abuse its discretion by failing to appoint counsel for Rouse because, to the extent Rouse had sought the appointment of counsel, he did not establish the requisite exceptional circumstances. See Terrell, 935 F.2d at 1017 (affirming refusal to appoint counsel where plaintiffs writing and legal knowledge were sufficient, matter was not substantially complex, and plaintiff was unlikely to succeed on merits).

Rouse’s remaining contentions are unpersuasive.

AFFIRMED.
