Bills' Mario Williams: Remains limited, coach optimistic

Williams was limited for the second straight day Thursday but coach Rex Ryan says he's not concerned about his availability for Sunday's game against the Dolphins, BuffaloBills.com reports.

We'll see if Williams gets a probable designation for Friday, but we'll take Ryan at his word for now and assume Williams will be on the field, trying to get the Bills' defensive line out of a season-long dry spell.
