Hardesty sustained a bone bruise to his knee during a 1-on-1 tackling drill before Cleveland's veterans reported to camp. Hardesty said he hurt his leg while making a cut.
Browns coach Eric Mangini said Hardesty, who has had a history of knee problems, will be limited in practice Thursday as the team prepares for Saturday's third exhibition game in Detroit. Mangini said Hardesty is questionable against the Lions "with the arrow pointed down."
The Browns traded three picks to Philadelphia to move up in April's draft and select him in the second round (No. 59 overall). He rushed for 1,345 yards last season at Tennessee.
