*243MEMORANDUM **

Emerson Paul Birdtail, II appeals from the 31-month sentence imposed following his guilty-plea conviction for assault resulting in serious bodily injury, in violation of 18 U.S.C. §§ 1153(a) and 113(a)(6). We have jurisdiction pursuant to 28 U.S.C. § 1291, and we affirm.

Birdtail contends that the district court procedurally erred by failing to address his arguments at sentencing and that his sentence is substantively unreasonable given his positive life changes. The record reflects that the district court did not procedurally err, and that the sentence is substantively reasonable. See United States v. Carty, 520 F.3d 984, 991-93 (9th Cir. 2008) (en banc).

AFFIRMED.
