The Browns are evaluating Chubb for a possible concussion after he was on the receiving end of a hard tackle from teammate Mack Wilson during Monday's practice, Mary Kay Cabot of The Cleveland Plain Dealer reports.
The incident occurred when Chubb reeled in a short pass before being met by Wilson, who hit him around the shoulder area. Chubb walked off the field with a trainer by his side and didn't return to practice, the Browns' first padded session of training camp. He'll presumably go through testing over the next day or two as the Browns look to confirm whether or not he sustained a concussion.
