ASHBURN, Va. (CBSDC) — Barring any setbacks, Robert Griffin III will be under center for the Washington Redskins on Sunday.

Griffin was able to fully participate during Friday’s practice — the first time he has done so this week. The rookie quarterback is listed as questionable on the team’s injury report.

“If he passes his tests and we don’t see any symptoms, then it looks like he’ll be ready to go,” head coach Mike Shanahan said.

Griffin has maintained he is not experiencing concussion-related symptoms and has passed the medical tests administered after each practice this week.

“Why would you not let somebody play if he’s felt good right at the end of the game [and] every day until now?” Shanahan said.

The Redskins say if Griffin were to experience symptoms prior to kickoff they were “not going to take the chance” of letting him play.

In other injury news, safety Brandon Meriweather continues to be sidelined with a suspect knee. Defensive end Doug Worthington was also ruled out after injuring his calf last week against the Falcons.

Wide receiver Pierre Garçon (foot) and cornerback Cedric Griffin (hamstring) are questionable.

Defensive tackle Barry Cofield (shoulder), cornerback DeAngelo Hall (knee) and running back Evan Royster (knee) are probable.
