Melvin Blackmon directly appeals after the district court 1 revoked his supervised release, and sentenced him to 18 months in prison. For reversal, he argues that the revocation sentence is substantively unreasonable.

Upon careful review, we conclude that the district court did not impose an unreasonable sentence. See United States v. Miller, 557 F.3d 910, 915-17 (8th Cir. 2009); United States v. Merrival, 521 F.3d 889, 890-91 (8th Cir. 2008). Accordingly, we affirm the judgment of the district court. We also grant counsel’s motion to withdraw.
