Bills' McCoy forced from game vs. Colts with head injury

Buffalo Bills running back LeSean McCoy was forced to leave Sunday's game against the Indianapolis Colts after suffering a head injury in the first quarter.

McCoy landed awkwardly after getting tackled out of bounds and was taken to the medical tent. He eventually went to the locker room with trainers and was later ruled out for the rest of the day.

Chris Ivory replaced McCoy as the lead back.

McCoy is the focal point of the Bills' offense and it would be a devastating loss if he misses any time.
