KSI made Logan Paul a boxing breast-ory with a points win, ironically, by a rookie mistake.
The money-grab rematch between the two YouTube sensations, 40 million fans, and a split decision after the split.
After weeks of false promises and empty threats, at least the tears at the end were real.
When Watford's 26-year-old social media star heard the judges scorecards had swung in his favor, he collapsed to the floor crying.
After the six-round slugfest, with the blood seeping from his bottom lip, KSI heard the scores of 56-55 and 57-54 for him Stop, he hit me with illegal shots, it was outrageous.
"But I do not stop. I have shut him up. Your boy is happy, victorious, happy days.
Idd I need to thank my team, Viddal Riley, Leon Wills, Larry Wade, Jeff Mayweather. They've helped me so much. Your boy has done it, I am victorious.
“KSI was scared to fight him, this time I went in there. Tonight I just kept going and going.
Saw Fans saw how much bigger he was, his physique. So I thought screw that! I'm going to work my a *** off. "
Paul had claimed to have been in KOING undefeated professional fighters in his sparring sessions but he really only hurt KSI when he was prostrate on all fours in the fourth.
After shipping a couple of short shots, KSI was pushed down to the canvas and Jack Reiss intervened, but not before Paul look another swing to the back of KSI's head.
Both men proved they have no place in professional boxing, no matter how much money and passing interest they can muster.
Paul told the world all week that he was going to become the heavyweight champion of the world.
Eventually a novice mistake from a boxing debutant cost Paul big time.
After doing the sums, he said: “Fair play to JJ – you are one of the toughest people I know, you deserve everything you have.
Wish I wish you the best. I know you're one of the toughest people I know. I don't like talking trash, it was all for the show, it was all for sell. I have nothing but respect.
Conditioning I was more comfortable than I was. Worked
“I think the two-point deduction was harsh, I'm not happy with that commission, I think if you do the math that cost me the fight.”
On bouncing back after being knocked down, KSI said: “It took me a minute or two to figure out how I was, I came back at it and kept going. That's boxing, man. I don't want people to think he's weak, he can't take punches.
“I've never worked so hard, in the ring and in the camp. I was ready and I was on fire. He couldn't deal with my jabs. He kept moving but I got him. ”
And to Logan Paul, he said: “It takes a big man to get in the ring, you're a big man.
Made You made me work today and last year. Thank you for a good fight. ”
KSI said: “This is done, he can go and do MMA. KS
As Logan Paul vowed: “You'll see me in the squared circle again, I'll be back!”
KSI was bar far more aggressive fighter and should have snatched the opening two rounds away. Paul, 24, even though he was at least throwing them.
The turning point was the fourth and with Paul the Ducted two points it was baffling to hear he was handed a win 56-55 by Zachary Young.
The action was entertaining and it will be back, no matter how grubby.
But the next set of contenders can save their boasts and bravado.
This is cheap exhibition boxing to settle silly grudges.
Hopefully the cost to real boxing, in the long-term, is not too great.
Both fighters were guaranteed to earn £ 700,000.
