KANSAS CITY, Mo. -- Chiefs linebacker Justin Houston left Sunday's 30-22 win over the Buffalo Bills in the first quarter with a knee injury and did not return.
Houston was taken to the locker room shortly after he was knocked down by a teammate, defensive back Ron Parker, during a play.
After the game, Chiefs coach Andy Reid said Houston has a sprained knee.
Houston leads the Chiefs with 7.5 sacks. He had 22 to lead the NFL last season.
