Stressing his diminished capacity, Christopher Tyrone Mack appeals his total 822-month sentence, imposed after he pleaded guilty to possession with intent to distribute narcotics and possession of a firearm in furtherance of drug trafficking. We lack jurisdiction to review the district court’s refusal to grant a downward departure: nothing in the record indicates that the district court incorrectly believed that it lacked to authority to depart downwardly. For background, see United States v. Dudley, 463 F.3d 1221 (11th Cir. 2006).

AFFIRMED.
