Pittsburgh Steelers running back Rashard Mendenhall may have a torn ACL in his right knee, head coach Mike Tomlin said according to Scott Brown of the Pittsburgh Tribune-Review.
Mendenhall was hurt following a five-yard run in today's 13-9 win over the Cleveland Browns. Mendenhall will undergo an MRI on Monday and is not expected to play in next weekend's AFC Wild Card Playoffs game against the Denver Broncos.
A 2007 first-round pick out of Illinois, Mendenhall led the Steelers with 928 rushing yards and nine touchdowns this season, falling 72 yards short of a third straight 1,000-yard season.
If Mendenhall is unable to play, Isaac Redman will be the team's primary running back with Mewelde Moore and rookie John Clay backing him up.
