Next week is our bye week. So if TL doesn't play against Wake he will have three full weeks to recover from his concussion. In my opinion, this means that CB should start the game at QB. I think we can beat Wake with him at the helm and it greatly reduces the risk of TL getting a second concussion and being out the rest of the season.
I'm sure the team doctors are keeping close watch on him. If he is still showing any symptoms I'm sure they will sit him. If TL is 100%, I really don't see any reason not to play him. Let's see how the week plays out.
