Redskins safety LaRon Landry (Achilles) and three offensive linemen are questionable for Sunday’s game against the Cowboys, Coach Mike Shanahan said.

Jammal Brown, Sean Locklear and Maurice Hurt are all dealing with injuries and if they can’t play, the Redskins face some big questions along the offensive line. If Brown and Locklear are unavailable, rookie Willie Smith would be the next option at right tackle.

It sounds like linebacker London Fletcher and safety Oshiomogho Atogwe will be healthy enough to play.

Shanahan has formally ruled out receivers Santana Moss and Niles Paul, along with linebacker Keyaron Fox.
