Washington Redskins coach Mike Shanahan is optimistic that Robert Griffin III will play next weekend after the rookie quarterback suffered a concussion in Sunday's game against the Atlanta Falcons.

Shanahan said that Griffin will rest before seeing an independent neurologist Monday evening. Griffin has not experienced any dizziness or headaches on Monday, and Shanahan said that the star rookie is "feeling good."

"We should find out in the next few days exactly what happens," Shanahan said Monday. "Right now it looks good. I'm not really sure if it stays that way. The professionals will monitor his situation and let us know if able he's able to play or not. We surely have nothing to do with it."

Shanahan described in detail the process Griffin will undergo, defended the decision to have the rookie described as "shaken up" during the game, and -- most importantly -- talked about ways to help prevent such an injury from happening again.

Griffin might participate in a cardio workout Tuesday and will practice Wednesday if he continues to avoid concussion-related symptoms. Shanahan acknowledged that the No. 2 overall draft pick will play against the Minnesota Vikings in Week 6 if he is able to practice this week.

Shanahan's update came hours after backup quarterback Kirk Cousins said Griffin was "in good spirits" on Monday morning during a mandatory meeting for rookies. Cousins also said Griffin "seems to be doing well."

Griffin is not allowed to speak to reporters until he is symptom-free. He was knocked out of Sunday's 24-17 loss in the third quarter on a legal hit to the helmet by linebacker Sean Weatherspoon while scrambling near the sideline.

"In my experience, when the quarterback gets that first hit like he received, they slide a little bit sooner in plays to come," Shanahan said. "They kind of protect themselves a little bit more."

Team spokesman Tony Wyllie said Griffin was examined by a neurologist in the locker room before being sent home from the team's stadium.
