I have went back and watched it a couple of times. He was on the sideline for the official timeout to get him off the field, a play that had a false start, and a play that went no where. So after staggering around and showing clear confusion as to where he was at he might’ve been out of play for two minutes of real time. I’m not a doctor but I don’t believe that’s enough time to be assessed for a concussion. On top of that it appears he puts hisself back in the game and no one does anything to stop it. No young person is going to want to leave the game. That’s where adults come in.
