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.
