The agreement gives the 27-year-old Romford fighter a fresh platform following a turbulent spell that included the first defeat of his professional career. Rather than ease back into competition, Fisher will immediately top the bill at ZUFFA BOXING 11 as the promotion continues to strengthen its heavyweight roster.

“The most exciting chapter of my professional career begins,” Fisher said. “Thank you to Dana White, Nick Khan, and the Zuffa Boxing team for this opportunity. Everything has led to this point. Bull Army, get ready to assemble. Bosh!”

Fisher earned widespread attention during his rise through the domestic heavyweight scene with an aggressive style that produced 12 knockouts from 14 victories. His latest outing saw him stop previously unbeaten Ivan Balaz in four rounds, restoring momentum after his rematch defeat to Dave Allen.

The Copper Box Arena has become a familiar venue for Fisher. September’s event will mark his third appearance there, giving him another opportunity to perform in front of a London crowd while beginning life with a new promoter.

The signing also represents another step in Zuffa Boxing’s expansion. After entering professional boxing under the leadership of Dana White and Nick Khan, the company has continued adding recognizable names, and Fisher becomes one of its most prominent British heavyweights.

An opponent has yet to be confirmed for the September 26 main event, with additional bouts expected to be announced as the card takes shape.

For Fisher, the move offers more than a change of promoter. It places him at the front of a growing platform and gives him the chance to rebuild his standing in the heavyweight division with a successful debut under the Zuffa Boxing banner.

Oleksandr Usyk has vacated his three heavyweight world titles but will not retire, promising at least one more professional outing before he hangs up the gloves, but in the eyes of one Hall of Famer, the Ukrainian has already ‘left the sport’.

Usyk struggled to overcome Rico Verhoeven back in Maywith a late and controversial stoppage sparing his blushes and denying boxing of one of it’s greatest ever upsets, leading to many saying that the ability of the 39-year-old fan-favourite has perhaps declined.

Following the fight, Usyk decided to vacate his WBA, WBC and IBF heavyweight marbles, with Murat Gassiev and Agit Kabayel being elevated to full world champions, whilst Frank Sanchez is expected to face either Moses Itauma or Bakhodir Jalolov for the vacant IBF strap.

Speaking on the Inside The Ring showformer two-division world champion and Boxing Hall of Fame inductee Tim Bradley said he believes Usyk has moved beyond the “sport” of boxing and into the “business” of boxing by choosing to relinquish his titles.

“I think that the Rico Verhoeven fight was an eye-opener for him to be honest with you. He struggled with him right, but then he was able to pull it off at the end.

“Relinquishing the titles, for me, you see the white smoke. He is done. He has left the sport of boxing, he is going to fight [again] but he has left the sport of boxing, he is in the business of boxing now.”

Usyk is currently being linked to a showdown with Deontay Wilder for what would presumably be his career finalealthough it remains to be seen whether a solid performance next time out could convince him to postpone his planned retirement.

Unified light-heavyweight world champion Dmitry Bivol is set to turn down a huge opportunity for another major fight, despite massive financial incentive.

Bivol collided with Artur Beterbiev in October 2024 in an instant classic light-heavyweight affair, but he came up short against the Canadian-Russian knockout artist, losing a majority-decision that saw Beterbiev claim the undisputed throne.

Just four months later, Bivol returned the favour and scored a majority-decision win of his own to avenge his solitary career defeat, putting an end to Beterbiev’s undefeated record and claiming the undisputed title for himself.

A third meeting has been mooted ever since, with Beterbiev remaining inactive in the 17 months that have followed, whilst Bivol returned to action with a win over Michael Eifert back in May.

Speaking with The RingIBA President Umar Kremlev revealed that Bivol is yet to accept a proposal for a trilogy showdown, in spite of the fact that he has been offered double the purse that he received for his other fights with Beterbiev.

“I’m very disappointed. Everyone is waiting for this fight. I don’t know why Bivol and his team are not accepting the offer, but I will do my best to make this fight happen. We’ve been having discussions with both teams for quite a while. I can confirm that Beterbiev and his team are ready for the fight.

“The offer we made to Bivol for the third fight was considerably bigger than the first two fights. Specifically, he was given two times a bigger offer than in previous fights. Beterbiev will fight for free just to make this fight happen.”

Continuing, Kremlev speculated that Bivol is seeking alternative opportunities but shared his thoughts that 41-year-old Beterbiev deserves the chance to reclaim his old belts, having agreed to an immediate rematch without hesitation after their initial encounter.

“To be honest, we’ve made really good offers in writing but unfortunately, Bivol’s team is still waiting for something. He appears ready for the fight, but his team is thinking.

“As far as I can see, it looks like they are looking for other opportunities and options in the market. I believe firmly that we need to find common ground and we need to make this fight happen. The world is waiting. Beterbiev gave Bivol a rematch and Bivol should do the same. It’s the only appropriate gesture.

“I can assure everyone that we are ready to organise the third fight at the highest level. We can stage the fight for 100,000 fans if it happens in Russia but are also open to bringing it wherever it needs to be. The most important thing is that the fight needs to happen. I’m confident it’s going to be another great fight.”

It is understood that Liverpool’s Callum Smith will likely be Bivol’s next opponentfollowing surgery on an injured elbow, with that contest expected to delay any Beterbiev trilogy until mid-2027.
