Craig Richards vs Radivoje Kalajdzic, Lee Cutler vs Louis Greene added to Johnny Fisher boxing bill at Copper Box Arena

Richards vs Kalajdzic will serve as the chief support bout to the 10-round heavyweight main event featuring Fisher at Zuffa Boxing 11 on September 26, live on Sky Sports .

An opponent for 'The Romford Bull' will be announced in the coming days.

Richards (20-4-1, 13 KOs) is a world-ranked former British champion who fought Dmitry Bivol for the WBA light-heavyweight title in 2021. He won his two most recent fights in 2025, including a knockout win over Dan Azeez last December.

The fight will mark the first time hard-hitting, Serbian-born Kalajdzic (30-3, 22 KOs) has fought outside North America as a professional. The 35-year-old's last fight was a seventh-round knockout victory against Oleksandr Gvozdyk in February.

The Copper Box Arena bill will also feature a 10-round middleweight showdown between British boxers Cutler and Greene.

Cutler beat Stevie McKenna on points when they fought in December 2024, marking the only professional defeat for Ireland's KO king so far.

Cutler's last fight saw him stop Aaron Sutton in his hometown of Bournemouth in three rounds, while Greene - a former Commonwealth super-welterweight champion - earned a points decision win over Daniel Buciuc in Dublin last week.

Decorated British amateur Kayla Allen is also fighting as part of her professional debut after becoming the first female fighter to sign with Zuffa Boxing.

Alex MacMillan, Leon Hughes and Fred Pullen, who is also turning professional, are also on the London bill.

Richards: My story isn't written yet - the time is now

Craig "Spider" Richards speaking on Sky Sports News:

"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."
