Promoter Eddie Hearn expects former WBC cruiserweight champion Tony Bellew (29-2-1, 19 KOs) to continue his career beyond the upcoming rematch with David Haye.
In 2017, Bellew moved up to the heavyweight division and pulled off a major upset when he stopped Haye in the eleventh round.
It was the only fight of the year for Bellew, after a planned December rematch with Haye was postponed after Haye suffered an injury in training camp and withdrew from the fight.
The rematch is now set for May 5, at the O2 Arena in London.
Hearn is expecting everything to go forward as planned, with Haye being fully fit for the second outing.
"I saw David Haye's social media today. He is private jetting from Vegas to LA. Very different camps, but that's David," Hearn told Sky Sports.
"David Haye wants to come back. He wants to try and be in big fights, he wants to try and fight for the heavyweight championship of the world. It's a big test for him. I'm expecting him to be 100 per cent. If he wasn't, I think he knows that's his career over. But for Tony Bellew, he believes he is going to end his career for him on May 5."
If Bellew wins the second time, Hearn expects him to continue fighting. At one point in 2017, Bellew was leaning towards retirement in the aftermath of beating Haye.
"I think there is plenty of fight left in Tony Bellew," said Hearn. "He's talking about one or two more fights. I think you might see him around for a while."
Who Bellew can fight is a good question, but the he's been trading words with comebacking heavyweight Tyson Fury in the last few months. If Bellew had his way, he would be facing Fury - who cleared all of the hurdles for his planned April return - by the end of the year.
