KSI and Swarmz will settle their rap beef in the opening fight of the night at The O2 arena in London, before the YouTuber heads back into the ring hours later for another bout.
The pair were once pals and recorded the top ten hit Houdini in 2020, which at the time was KSI's highest charting single. However, their relationship turned sour due to issues with promotional appearances for the record and they have now opted to settle their differences in the ring.
KSI was due to face Alex Wassabi in his boxing return after the American beat his brother Deji in March and has had to settle for an opponent with much less experience. In order to give fans value despite his lower level of competition, KSI will take on two fighters on the night, with Swarmz first up.
