If you are not sure then err on the side of caution, keep him out of games. Rams are done this season anyway.
This is a young man with wife and kids. We all know what happened to other football players who were not protected the right way when dealing with concussions.
If he really suffered another concussion in that short time it might be time to call it quits for him. Will always be grateful how he guided us to the SB victory .
Go Rams!!!!!!!!!!!!!!!!!!!!!!!!!!
