"The Washington Redskins listed tight end Chris Cooley as a limited participant in Wednesday's practice because of a knee injury.

Cooley, who missed all of the preseason with a balky knee, has appeared in all four of the team's games this season, but has yet to play a large role in the passing game, as he has in the past.

The last two games, he served primarily as the team's fullback. Wide receiver Anthony Armstrong (hamstring), cornerback Phillip Buchanon (neck) and running back Tim Hightower (shoulder) joined Cooley as limited participants. "
