MEMORANDUM **
Jorge Huerta-Avalos appeals his 57-month sentence imposed following his guilty plea to being found in the United States after illegal re-entry, in violation of 8 U.S.C. § 1326. We have jurisdiction pursuant to 28 U.S.C. § 1291, and we vacate and remand.
Huerta-Avalos contends that the district court violated his constitutional rights by imposing a sentence in excess of the two-year maximum set forth in 8 U.S.C. § 1326(a) based on a prior conviction that was neither proved to a jury nor admitted during the plea colloquy. This contention is foreclosed by United States v. Weiland, 420 F.3d 1062, 1079 & n. 16 (9th Cir.2005), cert. denied, — U.S.-, 126 S.Ct. 1911, — L.Ed.2d-(2006).
Huerta-Avalos also contends that the district court’s 57-month sentence was unreasonable. From the sentencing hearing record before us, we are unable to discern whether the district court understood the advisory nature of the United States Sentencing Guidelines, and whether the district court gave adequate consideration to the sentencing factors set forth in 18 U.S.C. § 3553(a). See United States v. Mix, 450 F.3d 375, 383 (9th Cir.2006). We therefore cannot determine whether Huerta-Avalos’ sentence was reasonable. See id. Accordingly, we vacate Huerta-Avalos’ sentence and direct the district court to explicitly employ the section 3553(a) factors at resentencing.
VACATED and REMANDED.
