Bills' Mario Williams out against Chiefs

The Bills are without two of their top pass rushers, Mario Williams and Kyle Williams, for Sunday’s game in Kansas City. Mario Williams is dealing with a foot injury, while Kyle Williams is due to have surgery on his knee.
Chiefs running back Charcandrick West is inactive with a hamstring injury, which means Spencer Ware will get the bulk of the carries. Knile Davis will also be in the mix.
