Washington Redskins quarterback Robert Griffin III, under siege during limited action versus Detroit on Thursday, exited early with a stinger and a possible head injury and was ruled out for the game.
Update: Griffin does indeed have a concussion. Expect him to miss some time.
RG3 averaged 12.0 fantasy points in the six games that he started and finished in 2014. That's what Blake Bortles averaged as the league's #24 fantasy quarterback. We know Griffin is capable of more, but he hasn't been the same player since his rookie season. Specifically, he's not running the ball as often or as effectively. A concussion would force him to miss valuable practice reps.
