The Tyson Fury fight is in the early afternoon so there really shouldn't be a scheduling conflict. We often see that when there is a big fight in Europe or the Middle East, promoters will still schedule events for later in the day in the United States. It would only be an issue if they also want to make Haney vs. Prograis a pay-per-view fight because people wouldn't want to spend on two different fights in the same day. Neither of these guys is popular enough for this fight to be worthy of being pay-per-view. Haney is just being a diva for whatever reason.
I actually understand why they wanted to move the date. But I think that is not actually necessary to be honest. I believe the Haney fight is going to be a good one anyway. And there is no reason for him to make such a fuss about changing the date.
Obviously, people are going to want to see the other fight. Tyson Fury versus Francis, those two are definitely much more popular. And also will be able to bring in a huge amount of money. Because we got the interest of two worlds, two sets of fans, in this fight.
