Former British light-heavyweight champion Craig Richards will face Serbia's Radivoje Kalajdzic in a 10-round showdown at London's Copper Box Arena on September 26.
The light-heavyweight contest will serve as chief support for Zuffa Boxing 11, which is headlined by a 10-round heavyweight main event featuring Johnny Fisher. Live television coverage will be broadcast on Sky Sports.
An opponent for Fisher, known as "The Romford Bull", is set to be announced in the coming days. The London bill will also feature a 10-round middleweight clash between British contenders Lee Cutler and Louis Greene, who engaged in an intense face-off when their fight was announced on Sky Sports News.
Light-heavyweight chief support clash
Richards, who holds a professional record of 20-4-1 with 13 knockouts, is a world-ranked former British champion who previously challenged Dmitry Bivol for the World Boxing Association (WBA) light-heavyweight title in 2021. The London fighter won both of his bouts in 2025, including a knockout victory against Dan Azeez last December.
Kalajdzic enters the fight with a record of 30-3 with 22 knockouts. The hard-hitting 35-year-old, who was born in Serbia, will be fighting outside North America for the first time in his professional career. In his last appearance in February, Kalajdzic scored a seventh-round knockout win against Oleksandr Gvozdyk.
Speaking on Sky Sports News, Richards expressed excitement about taking on the American-based puncher. "It's a very exciting fight. Everyone knows Kalajdzic can punch, I can punch, we've both been two fighters who haven't shied away from competition," Richards said. "We've been in with everyone, we've mixed it, we both probably want to push on now towards that world title and I feel like it's a great opportunity."
Richards added that the cross-Atlantic rivalry provides additional motivation for both men. "UK vs USA - that mix always goes down well! I'm up for it, I'm excited and I think this is now going to be the best version of me going into the new chapter and I get to go and display what I'm about," he said.
Richards targets world title push
Nicknamed "Spider", Richards believes joining Zuffa Boxing will allow him to stay active and secure high-profile fights. "I feel like my story is not written yet and I feel like I need to write it now," Richards said.
"The problem we had before is that a lot of opponents were turning [a fight with] me down, saying 'he's a hard fight, he's a long night in the office'. Zuffa doesn't allow you to do that, and that means I can get some activity. I can go out there and make a statement."
Middleweight showdown and professional debuts
The 10-round middleweight clash between Cutler and Greene adds further domestic rivalry to the card. Cutler enters the bout after stopping Aaron Sutton in three rounds in his hometown of Bournemouth. In December 2024, Cutler secured a points victory over Ireland's Stevie McKenna, inflicting the only professional defeat of McKenna's career to date.
Greene, a former Commonwealth super-welterweight champion, earned a points decision victory over Daniel Buciuc in Dublin last week.
The event will also mark the professional debut of decorated British amateur Kayla Allen, who became the first female fighter to sign with Zuffa Boxing. Debutant Fred Pullen will also feature on the card, along with Alex MacMillan and Leon Hughes.
The Zuffa Boxing 11 event takes place at London's Copper Box Arena on Saturday, September 26, with live coverage on Sky Sports and contract-free streaming via NOW.
