I thought Harold was already granted a medical redshirt? He's listed as a sophomore.

Can't even apply for a medical hardship until all of your eligibility is exhausted, including your redshirt. I would assume that he used his redshirt because he only played a small fraction of the season. Also, no such thing as a medical redshirt, only a medical hardship. We covered this fairly in depth on the old board, back when Hoskin's eligibility was exhausted.
