For a second straight day, Buffalo Bills defensive tackle Kyle Williams did not participate in practice as the team prepares for their Week 6 matchup with the Arizona Cardinals. Though head coach Chan Gailey remains optimistic that Williams will be okay to play on Sunday, it's never a good sign when a player misses two days of practice.

Even if Williams does play on Sunday - and there's good reason to be skeptical of that notion - it seems likely that he won't be at 100 percent. Neither will Marcell Dareus, who like Williams has been dealing with an ankle injury for a number of weeks. Spencer Johnson - who, you guessed it, has an ankle injury - did not make the trip out west with his teammates.

Folks, the run defense that has given up 558 rushing yards in the last two weeks may play on Sunday with only one completely healthy defensive tackle: Alex Carrington. Here's hoping that Williams is a viable option despite his ankle ding, and that Dareus will break out of his mini-slump this weekend.
