British ex‑world title contender Craig "Spider" Richards is set to clash with Serbian‑born heavyweight Radivoje Kalajdzic in a ten‑round light‑heavyweight bout, while fellow Briton Lee Cutler will meet Louis Greene in a middleweight contest. Both fights will headline the undercard of Zuffa Boxing’s Johnny Fisher event at London’s Copper Box Arena.
The Richards‑Kalajdzic encounter is slated as the premier support fight for the main attraction – a ten‑round heavyweight showdown featuring Johnny Fisher at Zuffa Boxing 11 on September 26, broadcast live on Sky Sports. The promoter has hinted that an opponent for "The Romford Bull" will be disclosed in the next few days, adding further intrigue to the card. Richards comes into the ring with a record of 20‑4‑1, including 13 knockouts.
He is a former British champion who earned a world‑ranking after challenging Dmitry Bivol for the WBA light‑heavyweight title in 2021. After a brief lull, he rebounded with two victories in 2025, highlighted by a decisive knockout of Dan Azeez in December of that year.
His blend of speed, power, and technical skill makes him a formidable adversary for any contender in the division. Kalajdzic, meanwhile, boasts a 30‑3 record with 22 stoppages.
At 35, the Serbian‑born fighter is known for his brutal punching power, having earned the nickname "The Serbian Nightmare" on the North American circuit. This bout will mark his first professional appearance outside of North America, a milestone that adds an extra layer of narrative to the matchup.
His most recent victory came in February, when he dispatched Oleksandr Gvozdyk by a seventh‑round knockout, reaffirming his status as a top‑tier threat in the light‑heavyweight ranks. The undercard also features a ten‑round middleweight clash between British pugilists Lee Cutler and Louis Greene. Cutler, who earned a points decision over Stevie McKenna in December 2024, has yet to taste defeat in the professional arena, making him a rising star to watch.
His most recent bout saw him halt Aaron Sutton in three rounds on Sutton’s home turf in Bournemouth, showcasing his finishing ability. Greene, a former Commonwealth super‑welterweight champion, earned a points win over Daniel Buciuc in Dublin just last week.
His experience at the elite amateur level and recent professional success position him as a credible opponent for Cutler, promising an engaging tactical battle. Adding further depth to the evening, decorated British amateur Kayla Allen will make her professional debut, becoming the first female fighter to sign with Zuffa Boxing.
Her transition from a decorated amateur career to the professional ranks underscores the growing prominence of women’s boxing in the UK. Alongside her, Alex MacMillan, Leon Hughes and Fred Pullen – who is also turning professional – will round out the London card, offering a full night of diverse talent. In a pre‑fight interview on Sky Sports News, Richards expressed his enthusiasm: "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. 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. 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.
I feel like my story is not written yet and I feel like I need to write it now. 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." Richards' comments highlight his desire to stay active and prove himself against a high‑caliber opponent.
Kalajdzic, known for his relentless aggression, will test Richards' defensive acumen and counter‑punching ability. The contrast of Richards' British boxing pedigree with Kalajdzic's North American experience promises a compelling stylistic showdown.
Fans can catch the entire event live on Sky Sports, with streaming options available for those without a traditional TV subscription. The promoter encourages viewers to use Chrome for optimal video playback.

Overall, the Copper Box Arena card offers a balanced mix of seasoned veterans, rising prospects, and historic firsts, making it a must‑watch night for boxing enthusiasts.
Whether you are drawn by Richards' quest for redemption, Kalajdzic's quest for global recognition, or the debut of Kayla Allen, the event promises high‑octane action and narrative depth that will resonate throughout the remainder of the 2026 boxing calendar.
