*655 Rolando Rosa Garcia appeals his conviction and sentence following a jury trial for conspiring to possess with intent to distribute 96 kilograms of marijuana and possession of the same. This court will not address Garcia’s argument, raised for the first time on appeal, that he was denied effective assistance of counsel because counsel failed to file timely objections to the Presentence Report. See United States v. Miller, 406 F.3d 323, 335-36 (5th Cir. 2005). Further, Garcia fails to meet his burden of showing that the district court’s sentence, which was determined by applying enhancements under the Guidelines, was plain error under United States v. Booker, — U.S. —, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005). Miller, 406 F.3d at 336-37; United States v. Mares, 402 F.3d 511, 520 (5th Cir. 2005), petition for cert. filed (Mar. 31, 2005) (No. 04-9517).

Without prejudice to Garcia’s right to claim ineffective assistance of counsel in a 28 U.S.C. § 2255 motion, the judgment of the district court is AFFIRMED.
