ASHBURN, Va. (AP) -- Washington Redskins coach Mike Shanahan says "right now it looks good" that Robert Griffin III will be able to play Sunday against the Minnesota Vikings.
Shanahan said Griffin was experiencing no dizziness, headaches or vomiting Monday, a day after the No. 2 overall draft pick suffered a concussion in a loss to the Atlanta Falcons.
Shanahan emphasized that Griffin will have to go through a series of tests to satisfy the NFL's return-to-play protocol. If there are any setbacks during the testing, the coach almost certainly will start Kirk Cousins or Rex Grossman against the Vikings.
Griffin was knocked out in the third quarter against the Falcons on a legal hit by linebacker Sean Weatherspoon.
