Jamaal Charles was the first, but not the only, Chief the Colts KO’d

Chiefs running back Jamaal Charles left in the first quarter of the Chiefs’ first-round playoff game against the Indianapolis Colts to undergo concussion protocol and will not return.

On only the sixth play from scrimmage Saturday, Charles came down hard on the tail end of a seven-yard run in which he was tackled by Indianapolis cornerback Greg Toler. Charles was later escorted to the locker room.

Charles had three carries for 18 yards when he left. He is the only player in the NFL to lead his team in both rushes and receptions.

Wide receiver Donnie Avery also left the game because of a concussion. He scored on a 79-yard touchdown reception.

Cornerback Brandon Flowers was helped to the locker room in the third quarter and was being evaluated for a concussion.
