ALLEN PARK -- Five starters did not participate in practice today (Wednesday).

Quarterback Matthew Stafford was on the field, but not throwing. He’s not expected to play this Sunday. We could get an update from Jim Schwartz after practice. Shaun Hill could be announced as the starter.

Safety Louis Delmas was out too. Last week Delmas didn’t practice on Wednesday and played on Sunday. But in the Lions’ loss on Sunday Delmas came off the field more than once limping, yet he went back in. So it’s unknown if taking today off is the plan or if his groin is worse.

Also missing were wide receiver Nate Burleson (ankle), linebacker Zack Follett and right guard Stephen Peterman.

Follett took a big hit while on special teams on Sunday and appeared to be groggy but went back in the game.

Peterman appeared to injure a knee in the loss on Sunday.

On Monday, Burleson said his ankle sprain would be reassessed today.

Both LB DeAndre Levy and DE Cliff Avril, who didn’t play on Sunday, participated in at least the beginning of practice. (The media is kicked out after individual drills.)

Also C Cody Wallace was signed to the practice squad while CB Jonathan Hefney was released from the practice squad.
