Washington Redskins quarterback Robert Griffin III was able to fully participate in practice on Friday. Griffin has expressed interest in starting Sunday's contest against the Minnesota Vikings after suffering what was diagnosed as a mild concussion last week against the Atlanta Falcons. If Griffin is able to pass another test on Friday afternoon he will play on Sunday, according to head coach Mike Shanahan. For the time being, Griffin is listed as questionable on the Redskins injury report.

According to Shanahan, wide receiver Pierre Garcon's foot was sore and is listed as questionable for Sunday. Garcon originally sustained the injury in Week 1 against the New Orleans Saints and has been dealing with lingering issues from the injury. In addition, cornerback Cedric Griffin (hamstring) is also listed as questionable for Sunday.

Running back Evan Royster (knee), Barry Cofield (shoulder) and cornerback DeAngelo Hall (knee) are all listed as probable. Defensive tackle Doug Worthington (calf) has already been listed as out and will be unavailable to play.
