Russell Wilson left Sunday's loss to the Kansas City Chiefs after his head slammed to the turf at the end of a run.
The Denver Broncos quarterback scrambled on a third-and-11 play early in the fourth quarter and broke toward the end zone after picking up a first down. He was tackled at the 2-yard line, and his head bounced off the ground at the end of the play. He remained motionless for a moment and was clearly woozy as trainers helped him to his feet.
Brett Rypien replaced him on the field as Wilson walked on his own to the sideline medical tent.
