Earlier today it was reported that KSI had defeated fellow YouTuber Logan Paul at the Staples Center in Los Angeles following a long-standing rivalry between the pair.
KSI emerged victorious in a split decision, with the judges scoring the match 55-56, 57-54 and 56-55 to the Brit.
The YouTube personalities first fought in Manchester last year but a majority draw was declared after six rounds - and so there was a lot riding on the highly anticipated rematch.In the build-up to the rematch, Logan Paul shared footage of his preparation for it:
And now, Logan Paul's brother, Jake has claimed the rematch was "rigged", and slammed the sport in a furious rant.
He accused KSI of "dining" with DAZN chief Joe Markowski the day before the match and spoke of the apparent corruption in boxing.
Talking to reporters in footage captured by iFL TV , Jake Paul said: "With that decision, that's just b*******.
"At the end of the day, I've been in this sport for a year now and, I probably shouldn't be saying this, but all this s*** is f****** rigged. You see people wining and dining each other, people at the Staples Center. Who was at the Staples Center last night with KSI? Joe Markowski. This sport is rigged, that's for sure."
He added: "The short amount of time I've been here, I've heard multiple stories about people paying stuff off, choosing fights, what time people sign contracts. It's not an excuse, I'm just saying."
Logan Paul had previously spoken about far he was willing to go in order to secure a victory, revealing that his coaches forbid him from having sex: "My coaches forbid me from having sex before my fight. they said I need to 'build my batch.' What’s a batch? Put quite simply, pent up ejaculate: my octane, if you will. Enough to sink a battleship."
And just like his brother, Logan is not taking the judges' score lying down. Following his defeat, in fact, he announced his decision to "contest the commission", the Mirror reports.
"I thought it was a legitimate knockdown," Paul said. "I didn't get a warning. I got two points taken away from me and that's the reason I lost tonight. I would love to contest the commission because I think I should have got a warning. I don't think it was fair at all."
