Buffalo Bills running back LeSean McCoy has what coach Sean McDermott called "ripped" rib cartilage, leaving him questionable for Sunday's game at Minnesota against the Vikings.
McCoy should not miss more than one game, if that, sources tell ESPN's Adam Schefter.
McCoy has had this injury before, and it is not expected to sideline him long.
McDermott described McCoy's status as day-to-day on Monday and didn't rule him out from playing on Sunday. McDermott didn't provide much detail on Monday except to say McCoy's status will be determined by how much pain he can tolerate.
ESPN earlier confirmed a report by NFL Network that McCoy had fractured ribs, but further testing Monday revealed the more definitive results.
McCoy suffered the injury in the third quarter Sunday when center Ryan Groy fell on him. McCoy was in obvious pain while walking around the locker room after the game. The six-time Pro Bowler declined an interview request because he was having difficulty speaking.
McCoy, 30, finished the game with 39 yards on nine carries, as well as four catches for 29 yards.
