After sustaining a "mild" concussion in Sunday's loss to Atlanta, Robert Griffin III wrote on Twitter that he "think(s)" he will play in Week 6.
The optimism sounds good, although Griffin still must pass tests from the league and an independent neurologist in order to be fully medically cleared for game action. "Thank you for all the prayers and support," Griffin tweeted. "I'm okay and I think after all the testing I will play next week." If Griffin doesn't receive clearance, Kirk Cousins would start against the Vikings.
