September 26: Johnny Fisher Steps Up Against Michael Pirotton in Heavyweight Main Event at Copper Box Arena in London

August 19, 2026 — British heavyweight star Johnny Fisher will return to his home turf against Michael Pirotton in the 10-round main event of ZUFFA BOXING 11 on Saturday, September 26, at London’s Copper Box Arena.

“The Romford Bull” will headline at the “Copper Bosh” for the third time, with thousands of the devoted “Romford Bull Army” expected to pack the arena.
Fisher (14-1, 12 KOs) makes his Zuffa Boxing debut following an eventful 2025 campaign that saw him suffer the first defeat of his professional career in a rematch against Dave Allen at the Copper Box Arena. Less than seven months later, he returned to stop the previously unbeaten Ivan Balaz in four rounds.
“I can’t wait to be back at the Copper Bosh on September 26 and bring another huge night of boxing to London,” Fisher said. “Bull Army, get ready, because it’s going to be a fantastic show. Pirotton is an experienced, powerful heavyweight who can’t be taken lightly.”
Pirotton (12-2, 6 KOs), a native of Liège, Belgium, made his professional debut in 2019 and won his first 10 fights. After dropping a pair of decisions to unbeaten foes in 2025, he rebounded this year with two stoppage victories. The 6-foot-5 Pirotton, who has defeated three previously undefeated prospects, has never been knocked down.
Pirotton said, “I have been working towards an opportunity like this my entire career, and the time has come. I know it’s going to be a massive crowd of Johnny Fisher fans, but I’ll be ready. Respect to Johnny and the Romford Bull Army, but he’s in for a tough night.”
Fisher vs. Pirotton tops a bill that also features a 10-round light heavyweight co-main event between Craig “Spider” Richards (20-4-1, 13 KOs) and Radivoje “Hot Rod” Kalajdzic (30-3, 22 KOs), as well as a 10-round showdown between British middleweights Lee Cutler (16-2, 8 KOs) and Louis Greene (19-4, 12 KOs). 
Welterweight Alex MacMillan (4-0, 3 KOs) and light heavyweight Leon Hughes (5-0, 4 KOs) will see action in separate six-rounders, while lightweights Kayla Allen and Fred Pullen will make their respective professional debuts.
ZUFFA BOXING 11 will be broadcast live on Sky Sports in the United Kingdom and Ireland and stream exclusively on Paramount+ in the United States and Canada.
