Bills' Mario Williams misses practice Wednesday

Buffalo Bills defensive end Mario Williams was held out of practice Wednesday due to a foot injury.

Williams suffered the injury during Monday's loss to the New England Patriots, and did not return.

With the Bills facing arguably their biggest game of the year against the Kansas City Chiefs on Sunday, Williams' return to practice would likely come as welcome relief for his club.

Defensive tackle Marcell Dareus was limited in practice due to a knee injury, while guard John Miller, and defensive tackle Kyle Williams were held out due to ankle and knee ailments, respectively.
