Fisher (14-1, 12 KOs) rebounded after a fifth-round knockout defeat by Dave Allen last May with a dramatic fourth-round finish of Ivan Balaz in December.

The 27-year-old, who turned professional in February 2021, already has his next bout booked.

The Essex puncher will make his promotional debut headlining Zuffa Boxing 11 at the Copper Box Arena on September 26 as the company's schedule in Britain and Ireland intensifies to end their first year.

Callum Walsh-Tyler Denny on Aug. 8 in Dublin will see Zuffa return to a fighter's home roots, two months after the success of Chris Billam-Smith's stoppage win over Ryan Rozicki in Bournemouth.

Monaghan's Aaron McKenna faces Etinosa Oliha for the IBF middleweight title on the same bill next month, while Fisher's loyal 'Bull Army' dubbed the 7,500-seater arena the 'Copper Bosh' after an explosive first-round knockout of Alen Babic in July 2024.

Having announced his free agency last month after being steadily built up through the domestic scene by Matchroom, the Tony Sims-trained heavyweight is looking forward to new beginnings.

This comes after rejecting an approach to fight Germany's Emanuel Odiase (11-0, 9 KOs) in May, having previously agreed terms to challenge Jeamie TKV for the British heavyweight title. TKV opted to face Richard Riakporhe on the Tyson Fury-Arslanbek Makhmudov undercard in April instead, suffering a fifth-round stoppage defeat.

"The most exciting chapter of my professional career begins," Fisher said in a press release.

"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!"

Further details regarding Fisher's opponent, undercard details and more will arrive in the coming weeks. The event will be broadcast live on Sky Sports (UK, Ireland) and streamed exclusively on Paramount+ in the U.S. and Canada.
