revenge on this upcoming rematch.
If I'm not mistaken, if by chance Naoya Inoue will win this fight against Nonito Donaire, he will now move on to the next weight class as that was planned for a long. It's just that, Donaire's chance to make a rematch becomes possible as he becomes a champion again and Inoue now has a purpose to unify it.
I'm not just familiar with the rules about the interim title and official title. Paul Butler got the interim WBO Bantamweight title but if my knowledge is correct, it will be upgraded to what Casimero is left. Anyone can correct me here. Therefore, there's a chance that Paul Butler's name will be involved in these Bantamweight Champions competition replacing John Riel Casimero.
Yes. It is automatic when a champion is removed or vacate a belt then an interim champion will be elevated as the new champion. Unless boxing politics stops it from happening. Paul Butler is the new WBO champion now. Casimero is still ranked number 1 in the WBO but I am not sure when can he get a mandatory shot at Butler considering how good and dangerous he is. Paul Butler will duck Casimero and will hand pick safer opponents for his voluntary defenses.
And if Inoue can beat Donaire, I think it is safe to say that there is a very very slim chance that Paul Butler will fight the monster. Donaire will have a better chance of unifying all the 4 belts considering he is also signed with Probellum, the same promoter of Butler. Paul Butler and Probellum knows it will be a suicide mission fighting Inoue. Unless Top Rank and ESPN (Inoue's promoter and network) overpays Butler which I also doubt. Probellum is more connected to PBC (Showtime and Fox) and it has some bantamweights in its stable. So they might try to hold the WBO belt in their network rather than throwing the belt to another rival network considering Butler would be a huge huge underdog over Naoya.
