KANSAS CITY, Mo. (AP) — Kansas City Chiefs safety Tyrann Mathieu has been ruled out for the remainder of Sunday’s divisional-round game against the Buffalo Bills after suffering a concussion while trying to make a tackle on the opening drive.
The Chiefs had held the Bills to fourth-and-2 at midfield when Allen took off on a designed run. Mathieu went low trying to tackle the 240-pound quarterback and his helmet collided with the knee of teammate Jarran Reed.
Mathieu was checked briefly in the blue sideline tent before he was taken to the locker room.
Allen converted that fourth-down run, then the Bills converted again on fourth-and-goal at the Kansas City 1 to take a 7-0 lead in a rematch of last year’s AFC title game won by the Chiefs.
