OPINION **

Appellant Mark Sleboda appeals the revocation of his supervised release and the resulting ten-month sentence imposed. Because he has now completed his sentence, we will dismiss his appeal as moot.

Sleboda’s underlying criminal sentence began in 2010, when the District Court sentenced him to forty-two months’ imprisonment and three years’ supervised release for violations of federal controlled substances laws. Sleboda completed his term of imprisonment in 2013 and commenced his period of supervised release. Before Sleboda’s supervised release period concluded, however, the District Court’s Probation Office filed a petition for revocation, citing instances of continued controlled substances possession. Sleboda admitted to some of the possession charges at the revocation hearing, and the District Court proceeded to revoke his supervised release and to sentence him to ten months’ additional imprisonment. Sleboda timely appealed. 1

On appeal, Sleboda’s counsel moves to withdraw pursuant to Anders v. California, 386 U.S. 738, 87 S.Ct. 1396, 18 L.Ed.2d 493 (1967), but both he and the Government contend that, because Sleboda has completed his ten-month sentence, his appeal is now moot. That contention rests on the constitutional requirement that where, as here, a previously incarcerated individual challenges the validity and terms of the judgment against him, “some concrete and continuing injury other than the now-ended incarceration” must exist for the individual’s challenge to present a live case or controversy. Spencer v. Kemna, 523 U.S. 1, 7, 118 S.Ct. 978, 140 L.Ed.2d 43 (1998). If such an injury does not exist, then the case is moot and we must dismiss it for lack of jurisdiction. See id.

Of course, collateral consequences flow from a criminal conviction, and thus a challenge to a conviction is not moot when the convict completes his term of incarceration. Id. at 8, 118 S.Ct. 978. But we do not likewise presume collateral consequences to flow from a supervised release revocation, United States v. Huff, 703 F.3d 609, 611-12 (3d Cir. 2013), and, even if a revocation could be used against a previously incarcerated individual in a future proceeding, that possible consequence is “a possibility rather than a certainty or even a probability” and does not provide a ground for federal jurisdiction, Spencer, 523 U.S. at 14-16, 118 S.Ct. 978.

Such is the case here. Sleboda has completed his sentence, and he cannot claim collateral consequences based on the possi *122 bility that his revocation will be used to his detriment in a future proceeding. Id. His appeal is therefore moot, and we lack jurisdiction to proceed further. See id. at 7, 118 S.Ct. 978.

For the foregoing reasons, we will dismiss this appeal.
