TEMPE, Ariz. -- Buffalo Bills defensive tackle Kyle Williams was supposed to practice today at Arizona State, but he missed his second straight session with an ankle injury.
Bills coach Chan Gailey didn't sound concerned about Williams' status for Sunday's game against the Arizona Cardinals.
"It's not the same one he had the surgery on," Gailey said, referring to the injury that ended Williams' 2011 season after five games. "We're just resting him. We think it won't be an issue for Sunday."
Reserve offensive lineman Chad Rinehart, expected to start in place of injured right guard Kraig Urbik, was healthy enough to practice Thursday in a limited capacity. Rinehart has been dealing with a calf injury that prevented him from finishing last Sunday's game in San Francisco and was unable to practice Wednesday.
Gailey said seeing Rinehart on the field Thursday "bodes well. We'll probably rest him [Friday], but we wanted to see what he had, and it was encouraging."
Bills center Eric Wood (foot) and safety Jairus Byrd (chest) each were limited for a second straight day but are expected to play Sunday.
On the Arizona side, cornerback Michael Adams (hamstring), linebacker Quentin Groves (hamstring), fullback Anthony Sherman (knee), cornerback Greg Toler (hamstring) and linebacker Reggie Walker (head) all did not practice for a second straight day.
All-Pro defensive tackle Darnell Dockett led a list of four players who were limited in practice for the Cardinals. Dockett is coming back from a hamstring injury. The others were tight end Jim Dray (knee), tight end Todd Heap (knee) and linebacker O'Brien Schofield (knee).
Running back LaRod Stephens-Howling, who has missed the past two games with a hip injury, practiced fully Thursday after being limited Wednesday. Others practicing fully for Arizona were running back William Powell (head), quarterback John Skelton (ankle) and guard Adam Snyder (elbow).
