UPDATED: Bills receiver Stevie Johnson sat out practice in the fieldhouse today.
Coach Chan Gailey said he was rested due to a sore groin. Johnson said he expects to practice on Friday.
"Stevie's been having a nagging groin for a month, so we just gave him a rest today," Gailey said after the team's workout.
Johnson was the only player not suited up, aside from cornerback Terrence McGee, who is out with a hamstring injury. Defensive tackle Torell Troup (sore back) was in uniform but was limited. Linebacker Arthur Moats (sore knee) was limited, too, Gailey said.
On Troup, Gailey said: "He couldn't go the full way, but he got better. He did a litlte bit more today than he did yesterday."
The Raiders have some major issues at receiver entering Sunday's game. No. 2 wideout Jacoby Ford (hamstring) did not practice and seems likely to be out. No. 3 wideout Louis Murphy (groin) is out.
