Buffalo Bills defensive end Mario Williams wasn't in the field house during the portion of today's practice that was open to the media. Williams said earlier he will play Sunday against the Houston Texans but suggested that he wouldn't practice until Wednesday.
Also missing from practice were defensive end Mark Anderson (knee) and guard Chad Rinehart (ankle). Cornerback Terrence McGee (knee) was present but didn't participate.
Some notable Bills did take part.
Left guard Andy Levitre, who Bills coach Chan Gailey revealed underwent a procedure on an unspecified injury last week (I guess we'll learn what it is when the injury report comes out Wednesday), took part in drills. Left tackle Cordy Glenn, out the past three games with an ankle injury, had his helmet on but mostly watched.
Right guard Kraig Urbik was involved. He has missed three straight games with an ankle injury, but said this morning he will play Sunday "no matter what."
Tight end Mike Caussin worked out for the first time since last season because of a knee injury. He is on the reserve/unable-to-perform list. The Bills now have 21 days to decide whether to keep Caussin or put him on season-ending injured reserve.
