The YouTube superstar is hoping to move one step closer to fighting the likes of Jake Paul and Tommy Fury as he seeks to build on his previous victories over Logan Paul and Joe Weller.
The O2 Arena is sold out for the MF & DAZN: X Series crossover event, which will see KSI open the card against friend and fellow rapper Swarmz, making his boxing debut as a late replacement for YouTuber Alex Wassabi, who had to pull out at late notice due to concussion.
After a raft of crossover bouts involving many other internet celebrities including KSI’s brother Deji, the Sidemen star will return for the main event some three hours later against a professional boxer in the shape of Luis Alcaraz Pineda, a Mexican with a record of 2-5 from his first seven contests.
Both bouts are at cruiserweight and will last for only three rounds each, the maximum allowed by the commission.
Here’s how to tune into the big fights live in the UK tonight...
