Craig Richards will face Radivoje Kalajdzic in the co-main event of Zuffa Boxing 11 at London's Copper Box Arena, while Lee Cutler and Louis Greene have also been added to the September 26 card.

Former world title challenger Craig Richards will face Radivoje Kalajdzic in a ten-round light heavyweight contest at Zuffa Boxing 11 on September 26.

The bout has been added as the co-feature to the event at London's Copper Box Arena, which is headlined by heavyweight star Johnny Fisher. Fisher's opponent is expected to be announced in the coming days.

Richards (20-4-1, 13 KOs) returns looking to continue his recent momentum after recording two victories in 2025, including a stoppage win over former British, Commonwealth and English champion Dan Azeez.

The Londoner is best known for his 2021 world title challenge against Dmitry Bivol, where he produced a competitive performance against the long-reigning champion.

Kalajdzic (30-3, 22 KOs) will be fighting outside North America for the first time in his professional career.

The Serbian-born contender impressed earlier this year at Zuffa Boxing 02, recovering from two knockdowns to stop former world champion Oleksandr Gvozdyk in the seventh round.

Lee Cutler and Louis Greene added to the undercard

The card will also feature an all-British middleweight contest between Lee Cutler and Louis Greene.

Cutler (16-2, 8 KOs) last appeared at Zuffa Boxing 07 in Bournemouth, where he stopped Aaron Sutton in three rounds.

Greene (19-4, 12 KOs) enters the fight following a points victory over Daniel Buciuc at Zuffa Boxing 10 in Dublin.

Several prospects have also been confirmed for the event.

Unbeaten welterweight Alex MacMillan (4-0, 3 KOs) and light heavyweight Leon Hughes (5-0, 4 KOs) are both scheduled to compete, while Team GB amateur Kayla Allen will make her professional debut in a six-round contest.

Essex lightweight Fred Pullen will also make his professional debut after a successful amateur career that included Senior Elite ABA and Haringey Box Cup titles.
