Concussion Protocol (and updates, please)

[Science Friction]

I don't know much about the concussion protocol and what a player has to do to be cleared to play. I know some players have made it back within a week while others have been out two to three weeks before making it back.

What all is involved in successfully moving through the concussion protocol and being cleared to play. I think that getting Trey back for the Titans game is essential for us coming out on top in that game.

Also, if you wouldn't mind, would you please post any updates on Trey's status in this thread as we move through the week and closer to Saturday's game? Also, if Trey doesn't make it back this week, what do you see is our best option to try to compensate for his loss?

Thanks in advance for your input.
