Montario Hardesty disclosed that his right knee injury was a bone bruise sustained during one-on-one tackling drills on the last day of Browns' rookie camp in late July.
The injury is unrelated to Hardesty's 2005 knee reconstruction. He won't play in this week's game, but he could see action in the Sept. 2 preseason finale against the Bears. Hardesty insists he'll be ready "way before the opener," and coach Eric Mangini is confident that he won't need "a ton of reps" to catch up. He already has a good handle on the offense after a strong spring.
