Marshall Ray Custard, Jr., pleaded guilty to transportation of a minor with intent to engage in criminal sexual activity, for which he was sentenced to 21 months of imprisonment to be followed by a three-year term of supervised release. He now appeals the 24-month prison sentence imposed upon the revocation of his term of supervised release.

Custard contends that the district court imposed a sentence above the statutory maximum. He argues that, under the principles announced in Blakely v. Washington, 542 U.S. 296, 124 S.Ct. 2531, 159 L.Ed.2d 403 (2004), and United States v. Booker, 543 U.S. 220, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005), the maximum revocation sentence that could have been imposed in light of his original sentence, based upon facts admitted by him, was 21 months, which was the top of the sentencing guideline range found applicable by the district court. He argues that 21 months, rather than the former statutory maximum of 15 years under 18 U.S.C. § 2423(a), governs the classification of his underlying felony for purposes of revocation of supervised release. See 18 U.S.C. §§ 3559(a), 3583(e).

Custard correctly acknowledges that his argument is foreclosed by this court’s decision in United States v. Alfaro-Hernandez, 453 F.3d 280, 281-82 (5th Cir. 2006), but he wishes to preserve the argument for possible further Supreme Court review.

AFFIRMED.
