Pittsburgh Steelers' starting running back Rashard Mendenhall left Sunday's win over the Cleveland Browns with a knee injury, and head coach Mike Tomlin told reporters after the game that he could have a torn ACL, according to multiple reports.
An MRI will be performed Monday to see the extent of the damage, ProFootballTalk reported. If nothing else, Mendenhall will certainly miss next weekend's wild-card matchup at Denver. Mendenhall has rushed for 890 yards and nine touchdowns on the season. Isaac Redman replaced Mendenhall Sunday, and will likely assume running back duties until his return.
