It could have a rematch (even if there is no written clause in the initial contract), if the fight is going to be razor sharp close or maybe even in a draw.
But if it's a convincing win, then maybe not, but if there is a huge money involved then again, they could go and fight one more before going up in weight. So I guess the fans will also have a final say and maybe the promoters are going to take that lead from us if they see a demand for it.
We never know, because that always depends on the winner if he will give a rematch, that's why to ensure a rematch will happen, it should be written in the contract. One example is the fight between Mayweather and Pacman, for some, they think it was a close fight, and both could make huge money again if Mayweather gave a rematch, but he choose not to fight again just to ensure he will keep his undefeated record.
Just curious. Maybe handlers are now doing that deal in regard to rematch, after realizing what happened with
Mayweather and Pacquiao both are hot and very sensation during those prime years, but the camp of Mayweather did not
give Pacquiao a chance to have another fight.
With the type of Crawford and Spence where there are many sponsors and advertisement the camp may include these rematch
from the contract that they will going to sign.
That would benefit the promoters more but it's necessary since it's a big fight. If a boxer refuses to rematch after a win, he can be sued since it's written in the contract, so he has no choice but to fight, and if he losses, then most likely a trilogy is gonna happen. With that possibility, it's good for the boxing community as we all know both fighters have a huge number of fans.
