WR Aldrick Robinson in training camp (John McDonnell/Washington Post)

Redskins coach Mike Shanahan said Thursday that receiver Aldrick Robinson passed his concussion tests and has been cleared to play. Robinson was knocked out prior to Sunday’s game during a collision with safety Brandon Meriweather.

Shanahan said cornerback Cedric Griffin (hamstring ) didn’t practice Thursday. Limited in practice were running back Evan Royster (knee) and receiver Brandon Banks (hip).  But
left tackle Trent Williams (knee) practiced fully.

Shanahan praised the production and mindset of Santana Moss, who has a reduced role at slot receiver this season, but came up with two catches on the game winning drive Sunday against Tampa Bay.
