Theory time: I think that we could get a sequence of events where JK is going to fight and Dan's grandmother is passing away, and like an ass JK will prevent Dan from either receiving the news or from going to his grandmother. He either will be a dick and say "do your job" or won't bother to hear Dan's pleas. This will definitely push Dan away until JK begins his redemption.
Also a wild idea from me is that JK may actually win the fight but will lose a lot more outside of it. He might lose Dan, but he might also lose his career if he pushes himself too hard or his opponent targets his shoulder and he is severely injured during the fight. That might be what pushes JK even more as he wins but he is unable to fight again or is temporarily placed into a break (which he would hate).
