ALLEN PARK — Louis Delmas returned to practice today (Thursday) after sitting out on Wednesday due to his ongoing left knee problem. It’s common for him to miss practice to rest his knee. The safety played every defensive snap in the opening game and 97 percent in the loss at Arizona.

Four others who didn’t work on Wednesday remained out — Reggie Bush (knee), Jason Fox (groin), Patrick Edwards (ankle) and Don Carey (hamstring).

Also linebacker Ashlee Palmer, who practiced Wednesday, was out. He was on the injury report last week with ankle injury.

If Bush can’t play on Sunday at Washington, rookie Theo Riddick and Mikel Leshoure will be expected to step up. Bush injured his knee in the second quarter on Sunday.

Fox missed Sunday’s game at Arizona with Corey Hilliard getting the start. 

Nick Fairley (shoulder) and Rob Sims (knee) were limited in Wednesday's practice. Both were on the field Thursday for the early portion that is open to the media.
