I think the story went something like this..
Harold leaves the TTU game saying he's injured
Trainers find out he's not really injured, call him a FP. Turns out Harold wanted to get out of the game because, well, we were getting our asses kicked and he was done with it.
Snyder sets up a meeting to address his being a FP, Harold says "F this I'm out" and never shows up and stops going to practice.
