Chiefs' Justin Houston forced from game vs. Bills with knee injury

Kansas City Chiefs linebacker Justin Houston will not return to Sunday's game against the Buffalo Bills due to a knee injury.

Houston limped off the field late in the first quarter and had his left knee attended to by trainers on the sideline. He was then taken to the locker room for further evaluation.

Houston has 30 tackles and 7.5 sacks on the season, and has been one of the league's most dominant pass-rushers.
