It's early and information regarding the extent of Mason's head injury is scarce but I would think a hit like that would take a few days at least before your head quit ringing, then another few days to a week to feel like myself. Let alone take any practice snaps, or be ready to study tape and be in starting shape for next week. Even if he says he's ready and makes an ok showing at practice you'd have to think that he would need more time. Would you chance starting Mason, see what Hodges can do, or see how Big Ben throws left handed?
