Medical redshirt? He's only been injured one time, this year, before any games were played. Best of my knowledge, he's taking a regular redshirt this year and he will have 2 remaining seasons left to play, 2015 and 2016.
Now, if he gets injured again - and plays less than x-number of games prior to the halfway point - he would be eligible to apply for a medical redshirt or hardship. Can't remember which one though.
If he plays in the bowl game, which I have no idea why he'd want to do that, he'd have one season left and that's it. I can't imagine anyone allowing him to do such a thing.
