The former 'Love Island' star had been due to return to the boxing ring against the former UFC star next month but says the bout is off due to Till's persistent claims that he would break boxing rules if he was losing towards the end of the bout.
Fury wrote on Instagram: "I can't believe I'm writing this but I am now not fighting Darren Till on 18 January 2025.
"For the one simple reason being that Darren has stated over and over that he does not want to abide by professional boxing rules and that if he is losing the fight he will resort to kicking and other stupid MMA tactics.
"I am a professional boxer, I have been out of the ring for over a year and I wanted this to be a great BOXING fight for the fans. I have wasted weeks in training camp."
Promoters Misfits Boxing are yet to confirm if the clash is off but Fury says his team are "working hard" to find a new opponent and fight date.
He said: "We are working hard to get a new opponent and date.
"I promise to get a better opponent and better fight for you guys. Good news around the corner."
In response to Fury's announcement, Till posted an angry video on the social media platform X denying that he would break the rules.
He said: "I said I'd kick him in the head at the press conference as a mental warfare tactic and since then I haven't said anything else.
"I've been hard at work boxing for two years, I haven't thrown a kick in two years, I threw one kick on a video as a mental warfare tactic.
"Never in a million years would I throw a head kick in a fight that is only boxing rules. I stick to rules, I have always abided by the rules throughout my whole career."
