Hamstring. Fitz will talk about it today in his news conference. If he can't go vs Iowa, or isn't 100% which could affect his running ability, that's huge as he was going for the 1st team all big ten slot this year.
VERY big. Will be watching for that news today, as I'm sure the rest of Hawkeye Nation will, too. Hate to see the guy hurt, but injuries are part of the game (as we know).
I'd rather have him play, because if he is out then we might relax and think this one is in the bag and then their backup comes in and catches us off guard.
