While attention will be drawn to the ring when Jake Paul and Tommy Fury face off, there is no denying that part of the spectacle is the show that comes alongside it.
There are expected to be plenty of superstars in attendance along for the ride, too.
The obvious big name to be there is Tyson Fury, the WBC champion and Tommy's brother. He has been in Saudi Arabia in the last week to lend support to his family member, and it would be a shock if he did not make an appearance in the crowd, or even in the corner.
Former heavyweight champion, Mike Tyson, will also be there as a guest of the event.
Al Nassr striker Cristiano Ronaldo will also be there, according to presenter Piers Morgan.
Devin Haney was slated for the press conference, so could have stayed on for an extra few days to take in the action, as could fellow fighter Shawn Porter.
Another possible is stand-up comedian and actor Kevin Hart, who is in Saudi Arabia for a gig of his own.
