Defensive end William Hayes tweaked his right knee a bit early in Thursday's practice, but said he was OK and expects to practice on Friday.
Hayes suffered a sprained MCL in his right knee on Aug. 11 and only returned to the practice field this week in preparation for the Oakland Raiders. He watched the majority of practice with ice on the knee.
“I'm fine. I just tweaked it a little today. It's nothing major, nothing that's going to set me back. I'll practice tomorrow and see how healthy it is,” Haynes said. “It was just kind of irritated today, and aggravated. But for the most part, I felt all right.
“It's one of those things where I feel it every now and then, and I just didn't want it to swell up on me or anything like that. It's fine.”
Hayes had previously indicated that he was ready for the season opener, but amended that slightly on Thursday.
'That still hasn't changed. It's up in the air. It's more of what Coach Fisher wants. If he wants me to play, I'll play. But like I said, it's up to Coach Fisher,” Hayes said.
While Hayes sat out, tackle Tony Brown (knee) and end Jacob Ford (back) both returned to practice.
Linebacker Colin Allred (ankle) did some work in team drills after being limited on Wednesday.
Guard Leroy Harris (ankle) and receiver Justin Gage (thumb) both practiced fully.
Guard Mike Otto (knee) remains out, as does veteran linebacker Will Witherspoon, who mother died unexpectedly on Tuesday.
