Wladimir Klitschko and David Haye will be ringside for the heavyweight clash between Anthony Joshua and Eric Molina.
The former heavyweight champions, who last fought in 2011, will watch Joshua attempt to defend his IBF title on 10 December at the Manchester Arena.
Haye, who lost his WBA belt to Klitschko in that 2011 fight after struggling with a broken toe, revealed that there will be no fireworks when the two meet ringside.
"I've seen him out and about a couple of times…we've settled our differences," the 36-year-old told Sky Sports.
"He came out on top so there is no real beef. I've always wanted the rematch, I've always wanted an opportunity to set the record straight and prove that wasn't me on my best night, but maybe that chance has gone now. You never know.
"If he goes out there and knocks out Joshua then a rematch with myself and Klitschko could be one of the biggest rematches.
"It's always good fun watching a rival in the ring doing their thing.
"When you are up there close at ringside, you can see every movement, every muscle, you can see the real rhythm, the timing. I always make sure that I get the opportunity, if possible, to see someone I may fight up close and personal."
