DENVER - Backup quarterback Brock Osweiler is active and available to relieve Peyton Manning in the Denver Broncos' playoff game against the battered Pittsburgh Steelers.

Osweiler missed nearly two weeks of practice with a sprained right knee before returning Friday.

With Osweiler available, the Broncos (12-4) deactivated QB Trevor Siemian.

Also out for Denver are DBs Shiloh Keo and Lorenzo Doss, running back Juwan Thompson, offensive linemen Sam Brenner and Robert Myers Jr. and nose tackle Darius Kilgo.

The Steelers (11-6) are without their top receiver and rusher with All-Pro Antonio Brown sidelined with a concussion and DeAngelo Williams out with an injured right foot.

Pittsburgh's other inactives are QB Michael Vick, cornerback Doran Grant, fullback Will Johnson, tackle Byron Stingily and defensive end L.T. Walton.
