It comes after one of Fury’s sparring partners was revealedRex
However, KSI, who is yet to be beaten in the ring, launched an astonishing X-rated attack on Fury after seeing who the boxer was sparring in preparation for the fight.
Taking to Instagram, KSI – who has 13.2 million followers on the platform – shared a picture of Owen Kirk’s boxing record to his story after Kirk shared an image sparring with Fury to his own page.
The Morecambe middleweight, 24, has a record of three wins, one defeat and two draws.
But KSI was not impressed by the calibre of opponent Fury was going up against, going so far as to accuse the Love Island star of not taking him seriously.
He wrote: “How f***ing dare you? You’re not taking me seriously at all you f***ing piece of s***.
“I’m preparing myself for the ULTIMATE challenge and THIS IS WHAT YOU’RE SPARRING WITH?!?!
“A middleweight with s*** movement and weak ass punches?!”
However, Kirk did not take the insult lying down.

Taking to X, formerly known as Twitter, Kirk replied: “@KSI six days until you are finished. Give me any of your fighters 160lbs – 180lbs.”
In KSI’s case, London Shootfighters head coach Alexis Demetriades revealed he has offered money to opponents to knock him out in sessions.
Demetriades said: “From where he was at when he first came to where he is now, he’s come on leaps and bounds.
“He’s only sparring professional boxers, this whole camp, forget MMA fighters, forget amateurs.
“He’s sparring guys 14-0, 13-0, 12-2, 8-0, 6-0, all with knockouts and all ranked by the British Boxing Board of Control.
“If they think that we’re not taking this seriously, we’ve got guys who are ranked higher than Tommy Fury in the gym.
“And they’re not just moving around, they’re trying to kill JJ and there’s bonus money on the table for them to knock him out.
“From a coaching point of view, all I want to do is put the correct guys in front on KSI and see whether or not he can deal with that and if he can’t then he shouldn’t be fighting.”
KSI is an underdog going into the fight considering the vast gap in experience in the ring between himself and Fury.
The last bout with a social media star Fury was in ended in a split-decision victory over Jake Paul.
Paul’s brother and KSI business partner Logan is fighting Dillon Danis on the undercard.
