Matchroom have options on the winner of Fuzile vs Ogawa as part of their deal. Winner will fight Cordina in early 2022. Zelfa vs Tarimo is a final eliminator for whoever comes out of those fights champion
But they fought a few months ago, and the fight was decent. And the fight was razor close, so what is wrong with that? Boxing needs more 50/50 fights, and rematches are valid when decisions are so close and disputed. They are both solid professionals, and evenly matched. Not sure why boxing fans would complain about that.
It depends on the venue and price. If this is 'pay per view' main event that's a disgrace. If it is main event on a routine weekly show, for a reasonable monthly subscription, or on free TV, that is fair enough.
