Chiefs running back Jamaal Charles exited the game after he landed on his head following a hit from the Jaguars' Paul Posluszny on Sunday in the third quarter.
Charles was diving for a first down on a third and one running play when Pozluszny tackled him and their helmets made contact. The hit sent Charles downwards, and the crown of his helmet landed first and he went head over heels.
After the play, Charles was attended to by trainers and walked off the field. He didn't return for the Chiefs' next series and after a brief stint on the exercise bike on the Chiefs' sideline, he limped to the locker room with what the Chiefs said was a quad injury. Not long after he went there, the Chiefs said Charles would miss the rest of the game. However, it wasn't especially needed -- the Chiefs held a 21-2 lead over the Jaguars at the time of Charles' departure.
Knile Davis, a rookie from Arkansas, and Cyrus Gray replaced Charles. Before he left the game, Charles had 14 carries for 76 yards, including a two-yard touchdown run.
