YouTube star KSI beat Joe Fournier with a controversial knockout on Saturday, finishing the former professional boxer with an accidental elbow. KSI, 29, landed the bigger punches throughout the first round of the exhibition bout at London’s Wembley Arena, and he tagged Fournier, 40, with a huge overhand right in Round 2. That was followed by an attempted right hook, with KSI (real name Olajide Olatunji) instead making contact with his elbow. The strike sent Fournier tumbling to the canvas and left him staring up at the ceiling, unable to beat the referee’s count. In a post-fight interview, KSI denied that he had stopped his fellow Briton with his elbow, before calling Tommy Fury into the ring for a face-off, which ended with the pair being separated. KSI’s controversial win was his fourth straight KO victory in as many exhibition bouts. The YouTube star, who rose to fame as a gamer but also raps, previously fought Logan Paul twice, drawing with his fellow YouTuber in an amateur bout and beating him on points in a professional rematch. Meanwhile, Fury – half-brother of world heavyweight champion Tyson Fury – is best known for his time as a contestant on Love Island, but he is also unbeaten as a pro boxer. The 24-year-old outpointed Logan Paul’s brother Jake in February. No fight between KSI and Fury has been scheduled, and for some time KSI has been exchanging words with Jake Paul in hopes of arranging a bout. Jake Paul has gone 6-1 as a pro after stopping KSI’s brother Deji in his amateur debut in 2018. Last time out, in February, 26-year-old Paul suffered his first loss, a points defeat by Fury. The YouTube star is now set to box ex-UFC fighter Nate Diaz in August. Click here to subscribe to The Independent’s Sport YouTube channel for all the latest sports videos.
