Roethlisberger is out indefinitely after spraining the medial collateral ligament in his left knee and sustaining a bone bruise. He was hurt in the third quarter of last Sunday's 12-6 win at St. Louis. Roethlisberger says he initially thought he broke his leg and was pleased his MRI revealed no extensive damage.
He does not believe the hit by Rams safety Mark Barron was dirty.
Michael Vick will start Thursday night when Pittsburgh hosts Baltimore. Roethlisberger isn't sure when he'll be cleared to return but hopes to be on the sideline in support if he can get off crutches by then.
