Cleveland Browns running back Trent Richardson was on the exercise bike at the beginning of Tuesday afternoon's practice, and he remained idle the remainder of the session with a sleeve on his left leg. After practice concluded, head coach Pat Shurmur said that Richardson was held out because of a sore knee, and that there is a chance he could miss Friday's preseason opener against the Detroit Lions. Starters normally play one quarter in the first preseason game, so that is the amount of action Richardson could end up missing.

Richardson had arthroscopic knee surgery back in the beginning of February and had been wearing a protective sleeve on his left knee during minicamp and OTA sessions with the Browns, according to Mary Kay Cabot of the Plain Dealer. This doesn't appear to be anything serious at this point, and coaches will gladly rest one of their top players in a rather meaningless exhibition game if they need to get back to 100 percent. We'll see if Richardson is held out of Wednesday's Family Fun Night at the stadium, where many fans were hoping to get their first look at the team's third overall pick.
