Teammate: Redskins' RGIII looks OK after concussion
Backup quarterback Kirk Cousins said he and Griffin attended a mandatory meeting for rookies Monday morning. Cousins said Griffin looked fine and was "in good spirits."
Griffin 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.
The No. 2 overall draft pick will have to go through the NFL's return-to-play protocol and before he is cleared to practice. He is also not allowed to speak to reporters until he is symptom-free.
Cousins finished the game in Griffin's place, throwing a touchdown pass and two interceptions.
