Rashard Mendenhall’s right knee injury has been officially diagnosed as a torn ACL.
The Pittsburgh Post-Gazette reports Mendenhall’s knee sustained no other damage, and that he will undergo surgery in 1-2 weeks. The news dings Pittsburgh’s hopes of advancing through an AFC Playoffs sure to be fraught with inclement weather, but is hardly a death blow for the Steelers’ pass-heavy offense. Mendenhall surpassed 20 carries in a game just once all season, and was at times outplayed by Isaac Redman. Although his injury is less severe than Adrian Peterson’s, Mendenhall will be in a race against time to be ready for Week 1 2012, and is a candidate to begin the year on the PUP list.
