British heavyweight Johnny Fisher will take on Belgian contender Michael Pirotton in a 10-round main event at the Copper Box Arena on September 26.
The bout marks the Zuffa Boxing debut for Fisher, known to his supporters as the Romford Bull, with the fight card broadcast live on Sky Sports.
Fisher enters the ring with a professional record of 14 wins and one loss, including 12 knockouts. The heavy-hitting fighter from Romford, Essex, rebuilt momentum with a stoppage victory over Ivan Balaz in December following a rematch defeat against David Allen in May.
The Copper Box Arena, situated in Queen Elizabeth Olympic Park in East London, will host the headlining fight as Fisher aims to push toward a shot at the British heavyweight title.
Michael Pirotton record and knockout form
Pirotton arrives in London with a professional record of 12 wins and two losses, having secured six of those victories by knockout.
The Belgian fighter made his professional debut in 2019 and built an undefeated start by winning his first 10 contests. After dropping two decision losses to undefeated opponents in 2025, Pirotton responded in 2026 by securing back-to-back stoppage wins.
While Pirotton has never been knocked down in his professional career, Fisher expressed confidence that his explosive power could deliver a stoppage finish.
"You want to get the knockout, you want to get the stoppage, but I've always said from the beginning of my career, I've got to win by whatever cost, the win is the most important thing," Fisher told Sky Sports.
"But with my power, my strength, my explosivity, of course I can draw a knockout or draw a stoppage," Fisher said. "Once I get someone hurt, I know I can finish them. I can smell when someone's feeling it or in trouble."
Title ambitions and main event slot
Fisher described the September contest as a critical opportunity for both fighters as he targets bigger fights in the heavyweight division.
"I'm excited, but I'm also driven and determined," Fisher said. "The next fight is always the hardest fight, and everyone I fight is a dangerous opponent because they're getting onto this show with Sky Sports, Zufa, with the Romford Bull Army there."
"It's a golden ticket for Michael Pirotton, but it's also my golden ticket because if I win, I get to go on to bigger and better things," Fisher added. "I've got ambitions in this game."
Fisher has built a passionate following known as the Bosh Army, or the Romford Bull Army. The September event is part of the Zuffa Boxing promotion co-founded by Ultimate Fighting Championship chief executive Dana White.
"I'm very very excited to show people what I can do," Fisher said. "You haven't seen the best version of the Romford Bull yet. We're going to try and show that on September 26."
