Misfits has been pivotal in the rise of ‘crossover boxing’, involving social media stars and celebrities contesting boxing bouts, but critics argue the promotional outfit – which has also staged gimmick tag-team fights – damages the integrity of the sport.

The organisation has parted ways from the Professional Boxing Association (PBA) and it is unclear which body would oversee a potential Misfits card featuring Khan.

Khan has previously held a boxing licence with the British Boxing Board of Control and most of his fights had been overseen by that governing body.

KSI, whose real name is Olajide William Olatunji, won on his pro boxing debut against Logan Paul in 2019 but lost his second fight, against Briton Tommy Fury, in 2023.

Khan, a 2004 Olympic silver medallist, retired from the sport in May 2022 with a record of 34 wins and six losses.

He tested positive for ostarine in a UK Anti-Doping test taken on 19 February 2022, the night he lost to Brook.

Khan accepted he broke anti-doping rules but said it was not intentional.

An independent tribunal accepted that argument, ruling out “deliberate or reckless conduct”.
