I don't think there is any way Bob will make it known before next Saturday. Could be wrong about that. Bob is so close to the vest about injuries. And I don't think they can know for sure.
He said in the post game that they didn't know about Baker's symptoms until halftime. He told them he was fine and answered their typical head injury questions. But at the half, he told one of the medical people that he had a little headache and they took his helmet away.
He will have to go through concussion protocol and they aren't going to know quickly. If he doesn't have a headache Monday, but does on Wednesday, then it could be a problem, even if all he has is a sinus headache.
I don't think we'll know before Friday, because I don't know if they'll know til then. But my guess is that even if they know, one way or another we won't. And even if Bob says one way or another, who would really trust what he'd say about a player's injury?
