On December 11, 2009, pursuant to a written plea agreement, Jemaine Sidney entered a plea of guilty to possession with intent to distribute 50 grams or more of crack cocaine in violation of 21 U.S.C. § 841(a)(1), (b)(1). The offense conduct occurred on or about March 12, 2009. In the plea agreement, Sidney stipulated to a drug quantity of at least 150 grams but not more than 500 grams. The Presentence Investigation Report attributed 252.91 grams of crack cocaine to Sidney, and Sidney objected to this finding.

On August 3, 2010, the Fair Sentencing Act of 2010 (“FSA”) was signed into law. Sidney moved to withdraw his guilty plea, contending that the enactment of the FSA constituted “a fair and just reason for requesting the withdrawal.” See Fed. R.Crim.P. 11(d)(2)(B). The district court denied the motion. At Sidney’s sentencing hearing on January 12, 2011, Sidney argued that he was entitled to be sentenced under the modified provisions of the FSA, which, inter alia, increased the quantity of crack cocaine required to impose the mandatory minimum sentence of ten years from 50 grams to 280 grams. See 21 U.S.C. § 841 (b)(1)(A)(ii) — (iii), (B)(ii)-(iii). The district court, in accord with our precedent at that time, instead sentenced Sidney under the law as it stood at the time of his offense and imposed a mandatory mini *848 mum ten-year sentence. Based on that ruling, and because Sidney stipulated to at least 150 grams and the Government argued for no more than 252.91 grams, the district court noted that a finding of a precise drug quantity was unnecessary to determine Sidney’s sentence.

Sidney appealed the denial of his motion to withdraw his guilty plea and his sentence, and we affirmed. See United States v. Sidney, 648 F.3d 904 (8th Cir. 2011), vacated, — U.S. -, 133 S.Ct. 66, 183 L.Ed.2d 705 (2012). Our judgment was vacated and the case remanded to us for further consideration by the Supreme Court in light of Dorsey v. United States, 567 U.S. -, 132 S.Ct. 2321, 2326, 183 L.Ed.2d 250 (2012) (holding that “the more lenient penalty provisions [of the FSA] apply to offenders who committed a crack cocaine crime before August 3, 2010, but were not sentenced until after August 3.”). We now vacate our prior opinion, vacate Sidney’s sentence, and remand the case to the district court for further proceedings consistent with the Supreme Court’s ruling in Dorsey.
