Redskins quarterback Robert Griffin III practiced fully and is expected to play Sunday against the Vikings, Coach Mike Shanahan said Friday. Griffin suffered a concussion in the third quarter of last week’s game against the Atlanta Falcons.

Receiver Pierre Garcon was limited in practice with his foot injury and is questionable for Sunday.  Cornerback Cedric Griffin (hamstring) also is questionable.

Defensive end Barry Cofield had treatment on an injured shoulder but is probable, as is cornerback DeAngelo Hall.

Ruled out are safety Brandon Meriweather (knee) and defensive end Doug Worthington (calf).
