Redskins rookie quarterback Robert Griffin III, who suffered a concussion last week, will start Sunday's game against the Minnesota Vikings, a league source has told Adam Schefter of ESPN. Griffin took part in the Redskins' full practice Friday for the first time this week. He had been limited in practice Wednesday and Thursday while recovering from a concussion suffered in last week's 24-17 loss to the Atlanta Falcons. Griffin was subject to NFL-mandated post-concussion medical tests he was required to pass before he could play. Source: The Redzone
If he had any sort of concussion symptoms, he should try to keep them the way he played today. Dude's balling out.
