Bills defensive tackle Kyle Williams missed Friday's practice with a back injury, putting his availability in doubt for Sunday's game against the Steelers.
"I'm concerned, no doubt," coach Rex Ryan said. "Last night it locked up on him. So we'll see how that goes. But obviously that's a big concern."
Williams, an 11-year veteran, has started every game this season and has played 81 percent of the Bills' defensive snaps, the most of any interior defensive lineman. His absence would likely mean larger roles for linemen Adolphus Washington, Jerel Worthy, Leger Douzable and Deandre Coleman, as well as fellow starter Marcell Dareus.
"If Kyle can’t go, we’ll definitely miss his presence on the field, his leadership, his skill set he brings to the table," Worthy said. "But at the end of the day it’s a rotating door with the league, so guys gotta be ready to play and everybody has to be ready to step up. This is a game that we have to have, so regardless – whichever 11 step on that field – we have to be prepared and ready to go."
Williams is officially listed as questionable for the game. The only player who is definitely out is linebacker Lerentee McCray (concussion). Ryan said receivers Robert Woods and Sammy Watkins should both be able to play in some capacity.
Brandon Spikes missed Friday's practice due to an illness while LT Cordy Glenn (back), TE Charles Clay (knee) and WRs Robert Woods (knee) and Sammy Watkins (foot) were limited.
