Chicago Bears defensive end Corey Wootton could miss four weeks with cartilage damage in his right knee, a league source confirmed Sunday night. The Chicago Tribune first reported the extent of Wootton's injury. Wootton hurt the knee covering the opening kickoff of the Bears 10-3 preseason victory over the Buffalo Bills on Saturday night.
