Former world title challenger Craig Richards will step into the ring against Radivoje Kalajdzic in a 10-round light heavyweight contest as part of Zuffa Boxing's Johnny Fisher card at the Copper Box Arena in London.
The same bill will see Lee Cutler and Louis Greene collide in a middleweight bout, adding further intrigue to a stacked night of action.
Richards versus Kalajdzic has been billed as the chief support fight ahead of the headline attraction on September 26 - a 10-round heavyweight main event starring Fisher, with the whole event broadcast live on Sky Sports.
Details of who 'The Romford Bull' will face in the ring are yet to be confirmed, though fight fans are told an opponent will be revealed within days.
Richards eyes redemption after Bivol defeat
Richards, who holds a professional record of 20 wins, 4 losses and 1 draw with 13 knockouts, carries genuine world-class pedigree into this clash. The Londoner previously challenged Dmitry Bivol for the WBA light-heavyweight crown back in 2021 and has since rebuilt momentum, winning both his outings in 2025 - including a stoppage victory over Dan Azeez this past December.
His opponent, Serbian-born Kalajdzic, brings an equally formidable resume to the table. The 35-year-old, who boasts a 30-3 record with 22 knockouts, will be stepping outside North American shores for the first time in his professional career. Kalajdzic arrives on the back of a seventh-round stoppage win over Oleksandr Gvozdyk this February, showcasing the kind of punching power that has made him a feared operator in the division.
Middleweight rivals renew hostilities
Elsewhere on the card, British duo Cutler and Greene will contest a 10-round middleweight showdown that promises fireworks.

Cutler has enjoyed a productive run of form, having outpointed Stevie McKenna in December 2024 - a result that stands as the sole professional loss suffered by the Irish knockout specialist to date. He followed that up by stopping Aaron Sutton inside three rounds on home soil in Bournemouth.
Greene, a former Commonwealth super-welterweight titleholder, arrives in good shape too, having claimed a points win over Daniel Buciuc in Dublin just last week.
The connection to Dublin's boxing scene continues elsewhere on the Zuffa Boxing calendar, with Aaron McKenna preparing to challenge for the vacant IBF title against Etinosa Oliha in the Irish capital, underlining the promotion's growing presence on both sides of the Irish Sea.
Debuts and rising talent complete the bill
Also featuring on the night is decorated British amateur Kayla Allen, who will make her professional bow having become the first female fighter to put pen to paper with Zuffa Boxing.
Alex MacMillan, Leon Hughes and Fred Pullen - the latter also set to turn professional - round out an eventful card at the Copper Box Arena.
Fans can catch Johnny Fisher's next outing live from London's Copper Box Arena on Saturday, September 26, exclusively on Sky Sports, with viewers able to access coverage via a Sky Sports subscription or a no-contract streaming option.
