He punched a wall or a locker.

Only thing that makes sense.

Get a little fired up, take it a little too serious and end up hurting themselves.

Holloway wasn’t going to lose to his former school, that’s a promise.

So he’s gotta leave it all in the locker room.

Sure, you got the win, but sitting at a hospital/urgent care late night?

No one wants that.

You know you’re in for a long night and you just want to sleep.

Got the win though, you know that’s all that matters to Holloway.
