Washington Redskins coach Mike Shanahan said that receiver Anthony Armstrong (hamstring), running back Tim Hightower (shoulder), cornerback Phillip Buchanon (neck) and tight end Chris Cooley (knee) all were limited in practice for a second straight day.

The coach said Cooley, who wasn’t limited in practice during the week leading up to Washington’s last game, had some swelling in his knee on Monday and had to have it drained. This is the same knee that gave Cooley problems during the preseason.

Shanahan said that he has encouraged players to continue to play hard, but to concentrate more on avoiding helmet to helmet hits by going a little lower.

Shanahan said he argued in defense of fullback Darrel Young’s hit in the Giants’ game but that hits by Perry Riley and Niles Paul both were helmet to helmet.
