Kelvin Worth was sentenced to 200 months in prison following his plea of guilty to possession with intent to distribute and distribution of crack cocaine in violation of 21 U.S.C. § 841. Following amendments to the Sentencing Guidelines that lowered the base offense levels for crack cocaine offenses, the district court granted Worth’s motion for sentence re *15 duction under 18 U.S.C. § 3582(c)(2) and reduced Worth’s sentence to 151 months, the minimum sentence under the amended Guidelines. Worth appeals and challenges the limits on the district court’s discretion set forth in U.S.S.G § 1B1.10 and argues the district court had the authority to impose an sentence below the minimum in light of the Supreme Court’s ruling in United States v. Booker. 1 The Government has moved for summary affirmance, asserting that the district court could not reduce Worth’s sentence further. Alternatively, the Government moves for an extension of time to file a brief.

Worth’s arguments fail in light of our recent decision in United States v. Doublin. 2 Accordingly, the Government’s motion for summary affirmance is GRANTED, and the judgment of the district court is AFFIRMED. The Government’s alternative motion for an extension of time to file a brief is DENIED as moot.
