Oleksandr Usyk celebrates
Oleksandr Usyk retained his WBA, WBO and IBF titles by winning his rematch with Anthony Joshua

Frank Warren says a fight between Tyson Fury and Oleksandr Usyk will happen.

The champion said he would not retire. He said after Usyk's victory that he would destroy them.

He and Usyk would be a great fight.

It will be a fight because both teams want to see that happen.

Lewis beat Holyfield in 1999 to become the last undisputed champ.

There has never been a fight where all four belts were on the line.

After 33 fights, he's still perfect. Usyk said he wouldn't fight if he wasn't fighting Tyson Fury.

He said after the fight that Tyson was the only fight he was interested in.

It's just a matter of where it will make the most money.

For the first time, God knows how long the belts are on the line. They are both perfect. The entire world of boxing will be interested in this fight.

Joshua failed to regain the titles he lost to Usyk in September.

Although Joshua has lost his belts, Warren said there could still be a fight between the two.

He believes Tyson will beat Usyk and that a fight between the two could happen.

You can't think about fights like that until he reestablishes himself.
