Eric Decker leaves with knee injury

DENVER -- Broncos wide receiver Eric Decker was knocked out of Sunday's AFC wild-card playoff game after being hit in the left knee by Pittsburgh linebacker James Harrison.

Decker, the team's leading receiver, was helped off the field and went straight to the locker room. The Denver Post reported that he suffered a sprained MCL and will not play in Saturday night's divisional game against the New England Patriots.

Decker was scheduled to undergo an MRI on Monday, the newspaper reported.

The second-year receiver hauled in a pass over the middle, but was immediately tackled by Harrison, who went low to bring Decker down on a play first ruled a catch and then overturned on replay.

Harrison has a history of hits to the head. He was suspended last month because of his helmet-to-helmet hit on Cleveland quarterback Colt McCoy, who suffered a concussion.

Already banged up on the offensive line, the Steelers had left tackle Max Starks leave with a right knee injury. They were already without All-Pro center Maurkice Pouncey, who missed the game with an ankle injury.

Pittsburgh defensive linemen Brett Keisel (groin) and Casey Hampton (left knee) left with injuries.

The Broncos won 29-23 in overtime.
