Arnett Bonner appeals the 112-month sentence the district court 1 imposed after granting the government’s Fed.R.Crim.P. 35(b) motion to reduce Bonner’s sentence based on substantial assistance. Upon careful review, we conclude that we lack jurisdiction to review Bonner’s appeal. See United States v. Haskins, 479 F.3d 955, 957 (8th Cir. 2007) (per curiam) (jurisdiction over appeal of Rule 35(b) sentence *705 is governed by 18 U.S.C. § 3742(a); although defendant framed issue as sentence’s overall reasonableness, he was appealing court’s ruling on motion to reduce sentence, and court lacked jurisdiction because he did not satisfy § 3742(a) criteria). Accordingly, we grant counsel leave to withdraw and we dismiss this appeal for lack of jurisdiction.
