MEMORANDUM **
Juan Acosta-Tovar appeals from his thirty-month sentence following his guilty-plea conviction for being a previously deported alien found in the United States in violation of 8 U.S.C. § 1326(a). We have jurisdiction pursuant to 28 U.S.C. § 1291.
Acosta-Tovar contends that the district court violated his constitutional rights by making an upward adjustment under U.S.S.G. § 2L1.2(b)(1)(C) on the basis of his prior state conviction for cocaine possession, which the district court found to be an aggravated felony. He argues that a jury should have determined the nature of this prior conviction. This contention is foreclosed by United States v. Esparza-Gonzalez, 422 F.3d 897, 907 (9th Cir.2005), and United States v. Brown, 417 F.3d 1077, 1079-80 (9th Cir.2005).
Because Acosta-Tovar was sentenced under the then-mandatory Sentencing Guidelines, and we cannot reliably determine from the record whether the sentence imposed would have been materially different had the district court known that the Guidelines were advisory, we remand to the sentencing court pursuant to United States v. Ameline, 409 F.3d 1073, 1084 (9th *881Cir.2005) (en banc). See United States v. Moreno-Hernandez, 419 F.3d 906, 916 (9th Cir.2005).
REMANDED.
