*1 Before: LEAVY, WATFORD, and FRIEDLAND, Circuit Judges.

Gerry Johns, a California state prisoner, appeals pro se from the district court’s summary judgment in his 42 U.S.C. § 1983 action alleging deliberate indifference to his serious medical needs. We have jurisdiction under 28 U.S.C. § 1291. We review de novo. Toguchi v. Chung , 391 F.3d 1051, 1056 (9th Cir. *2 2004). We affirm.

The district court properly granted summary judgment because Johns failed to raise a genuine dispute of material fact as to whether defendant Zamora was deliberately indifferent in treating Johns’ forearm injury. See id. at 1057-60 (a prison official acts with deliberate indifference only if he or she knows of and disregards an excessive risk to the prisoner’s health; negligence and a mere difference in medical opinion are insufficient to establish deliberate indifference); Hallett v. Morgan , 296 F.3d 732, 746 (9th Cir. 2002) (prisoner alleging deliberate indifference based on delay in treatment must show that delay led to further injury).

AFFIRMED.
