Arizona state prisoner William Watson appeals pro se from the district

* This disposition is not appropriate for publication and is not precedent except as provided by Ninth Circuit Rule 36-3. ** The panel unanimously concludes this case is suitable for decision without oral argument. See Fed. R. App. P. 34(a)(2). 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. 2004). We affirm.

The district court properly granted summary judgment because Watson failed to raise a genuine dispute of material fact as to whether Weigel was deliberately indifferent in treating Watson’s hernia. See id. at 1057-60 (holding that deliberate indifference is a “high legal standard” requiring a defendant be aware of and disregard an excessive risk to an inmate’s health; medical malpractice, negligence, or a difference of opinion concerning the course of treatment does not amount to deliberate indifference).

We do not consider arguments and allegations raised for the first time on appeal. See Padgett v. Wright, 587 F.3d 983, 985 n.2 (9th Cir. 2009).

Watson’s motion for an extension of time to file a reply brief (Docket Entry No. 24) is denied as unnecessary.

AFFIRMED.
