Redskins coach Mike Shanahan said that wide receiver Pierre Garçon, cornerback Josh Wilson and safety Brandon Meriweather all remained limited in practice Thursday.

Garçon continues to be hampered by an injury to his right foot, Wilson by the mild concussion he sustained Sunday, and Meriweather the knee injury suffered the first week of regular season practices.

Shanahan said Garcon hasn’t had any additional tests on his foot because the extent of his injury is known. Garcon remained on the field after practice to take some stationary passes, but still hasn’t been able to go full speed.

The availability for all of those players for Sunday’s game remains uncertain.
