Oakland Raiders receiver Amari Cooper exited Sunday's game against the Kansas City Chiefs in the second quarter with an apparent leg injury and is questionable to return.
Cooper had his leg rolled up on from behind as he was blocking on a running play. He was tended to on the sidelines.
Cooper sustained an ankle injury and a concussion on a hard hit in Week 12 and missed last week's game. He was cleared from concussion protocol and recovered enough from his ankle injury to be activated for Sunday's game.
