This weekend, X Series 017 (live on DAZN) will take place at Dublin's 3Arena, and it will be headlined by a big crossover bout.
Former Premier League footballer Danny Simpson will step into the ring to take on streamer and YouTuber Danny Aarons on a card that will also see KSI perform new music live at the event.
With Simpson's involvement, KSI was asked during an exclusive interview with DAZN about the possibility of another footballer appearing on a future Misfits show in Wayne Rooney.
Rooney, who has a boxing background, has expressed an interest in getting involved with the Misfits, however, KSI believes the current Plymouth boss may have to work to be fight-ready.
He said: "Yes, he does, but I think he's probably going to have to lose a bit of weight before he gets into the ring.
"But if he's actually serious about wanting to fight, then Misfits have their arms wide open."
