KSI warns that by the time he’s done with Dillon Danis, there won’t be much left of him for Tony Ferguson to fight.

For context, KSI is set to square off against Danis in a 185-pound grudge match in the main event of Misfits Boxing 21 on March 29 at the AO Arena in Manchester, England.

However, following his sophomore appearance in the boxing ring, "El Jefe" is booked to compete against former UFC interim lightweight champion Ferguson under the banner of the newly launched MMA promotion, Global Fight League (GFL), with the bout tentatively scheduled for May 11.

On Tuesday, the YouTuber-turned-influencer boxer, who has a long-standing feud with Danis, took to X to issue a chilling message just two weeks ahead of their showdown. His words weren’t just aimed at Danis as they also carried a veiled shot at Ferguson, with "The Nightmare" vowing to punish Danis so brutally that his anticipated MMA return would become an afterthought.

"I don't think people understand what I'm about to do to Danis. His fight with Ferguson will be dead. His UFC dreams will be dead. His career in combat sports will finally be dead," KSI wrote on X.

KSI and Danis were originally set to face off in January 2023, but "El Jefe" pulled out just a week before fight night without offering a clear explanation. His last-minute withdrawal only added fuel to their already heated rivalry, as they have traded barbs on social media on several occasions.

"The Nightmare" was last seen in action in October 2023, headlining the MF & DAZN: X Series 10 – PRIME Card against Tommy Fury, where he suffered a controversial unanimous decision loss.

Meanwhile, Danis made his boxing debut on the same card, taking on KSI’s former adversary and now collaborator, Logan Paul. But the bout took a wild turn when the outspoken MMA fighter attempted to lock "The Maverick" in a chokehold, resulting in his disqualification in the sixth round.
