Cincinnati wide receiver Mohamed Sanu will undergo potential season-ending surgery Monday for a stress fracture.
Bengals coach Marvin Lewis said via The Cincinnati Enquirer on Friday that the injury occurred during practice Thursday and that Sanu likely will be out for the year. He is expected to be placed on injured reserve.
Sanu, a rookie from Rutgers, emerged as a pass-catching complement to A.J. Green in the past five weeks, catching 16 catches for 154 yards, including four touchdown receptions in the last three games.
