I just wonder what is next for Usman. The guy still has champions ambitions, but he is rather old already. 37 and already 8 years in UFC. He wont get a title fight as a next fight. Imho he wont have a title fight in the fight that comes after his next (if he wins). 2 fights that is like a year in fighters career.
He's 36, he'll be 37 in May, not that this makes any real difference. There are plenty of potential match-ups for Usman that would make sense. He's still the number one contender, so probably will be matched against Belal, and the winner will get a title shot. This would work best if Colby defeats Edwards. Usman beat Colby twice already, so it would be a sort of test to see if he's still there in terms of fighting ability.
Alternatively, he could be paired up with some rising new star like Shavkat Rakhmonov, but I think the first option is much more likely to happen.
