Jason Peters misses practice; Michael Vick limited

Tackle Jason Peters did not participate in practice on Wednesday with a shoulder injury. It's still early in the week, but coach Chip Kelly said Monday he expected Peters to return on Wednesday.

Peters, a starting left tackle, briefly left last week's game before returning. The injury is important to monitor as the week progresses.

Running back Chris Polk was absent with a shoulder injury.

Quarterback Michael Vick was limited as he continues to recover from a hamstring injury. Punter Donnie Jones (foot) and safety Patrick Chung (shoulder) were also limited.
