Tight end Chris Cooley was limited in practice for the third day in a row on Friday as he continued to work through a knee injury.
He was officially listed as questionable for Sunday's game against the Philadelphia Eagles.
Cooley had to have his knee drained of excess fluid last week. It's a minor procedure but coaches want to be cautious with the knee.
"It's always a concern," head coach Mike Shanahan said. "He is better. The first day was his worst and the last couple days were a little bit better, so hopefully there is no setback."
Cooley has been able to play in all four of the Redskins' games this season despite the lingering knee injury. He has seven catches for 66 yards through the first four games.
If Cooley is unable to play or is limited in Sunday's game vs. Philadelphia, Fred Davis will likely see the bulk of playing time at tight end.
After Friday's practice, Cooley said he was keeping on top of his knee and preparing every day in practice.
"I'm fine, it's something I'm managing," Cooley said. "I get myself ready to practice and play every day."
Cornerback DeAngelo Hall was added to the Redskins' injury report on Friday due to a knee injury suffered in practice.
Hall was listed as questionable for the Eagles game.
Cornerback Phillip Buchanon (neck), wide receiver Anthony Armstrong (hamstring) and running back Tim Hightower (shoulder) were also listed as questionable.
