As much as the spotlight will be on Dillian Whyte and Dereck Chisora on Saturday night, it's also going to be a huge occasion for David Haye.
The former world champion confirmed his retirement in June and has now taken his first steps into management, a move he announced with the shock decision to team up with his old nemesis, Chisora.
In the build-up to this weekend's fight, the focus within camp has been about changing the 34-year-old's image.
That has entailed changing his nickname from 'Del Boy' to 'WAR' and while that might seem trivial, it is all about a change of mentality.
With that in mind, Haye is already talking up a fight between Chisora and Anthony Joshua, if the former can overcome Whyte.
Indeed, it's possible that AJ will be eyeing the winner in April 2019.
Even if he had wanted to fight Deontay Wilder or Tyson Fury - and that's debatable - they are now going to be preoccupied with gearing up for a rematch following their draw in early December.
Joshua may hold three of the four major titles, but as far as many boxing fans are concerned, nobody will know how good he really is until he steps into the ring with Wilder or Fury.
The 2012 Olympic gold medalist doesn't seem keen, judging by the recent negotiations with Wilder's team.
Ahead of Whyte vs Chisora, the question was put to Haye by Sky Sports Boxing whether he thinks he would have beaten Joshua in his prime.
How would Haye vs AJ have turned out?
And he answered in just the manner you'd expect:
"I'd have done way better than anyone else he's stepped in the ring with," Haye replied.
"There's nobody else that's been able to make him miss and make him pay.
"I think the only person who had the ability, possibly, was Povetkin, but when he fought him, Povetkin was past his prime."
When pressed on whether he'd have knocked Joshua out, Haye added:
"I think a peak David Haye would beat pretty much anybody.
"In my mind, when I was in my heyday, I felt invincible. On my day, I think I'd beat pretty much anybody."
Sadly, we'll never know - though Wladimir Klitschko might have something to say on that particular debate, as a man who has fought both.
It's over to Joshua to step into the ring with a genuine contender next year and then, perhaps, he will go some way towards silencing his critics.
