KSI scored a huge split decision win over fellow YouTube personality and rival Logan Paul in their Los Angeles grudge match.
Fighting under professional boxing rules, the pair fought out a thrilling rematch with the Briton walking away with the win on the judges' scorecards.
The decisive moment came in the fourth round where Paul landed an uppercut on KSI - forcing him to take a knee.
The American landed a shot on his opponent while he was still down however, and was promptly deducted two points by the referee.
That move proved costly as KSI did enough to get the points win.
