The Bills came out of last week’s victory with some hobbled players. Sammy Watkins and John Miller both left Buffalo’s Week 3 game in Miami in the first half with calf and groin injuries. LeSean McCoy said his hamstring acted up on him and he too exited the game prematurely. And Aaron Williams missed the game after sustaining a neck injury that initially sent him to the hospital in Week 2. Head coach Rex Ryan delivered some sobering news on Wednesday indicating all four could miss Sunday’s home game against the Giants.
