Chris Ivory

Buffalo Bills running back LeSean McCoy left in the first quarter of Sunday's game against the Indianapolis Colts after suffering a head injury, the team announced. He was ruled out from returning.

Chris Ivory was also hurt after McCoy went down but his status is still up in the air. It left Marcus Murphy as the team's RB.

McCoy was injured after he was hit out of bounds on a 1-yard run on Buffalo's opening drive. He was on the ground briefly before walking into the sideline medical tent under his own power. He was then accompanied by a trainer to the Bills' locker room.
