Boxing fans had better keep their diaries free for 15 December, as it's shaping up to be quite a hectic day.
KSI and Paul will now be battling it out to rake the most viewers in - possibly reigniting their long-standing rivalry.
Speed has been taunting his rival in recent weeks and urged him to put his money where his mouth is by stepping into the ring with him.
KSI finally conceded, saying: "December 15th, come through and let’s do this."
He then simply uploaded a promo poster for the fight to his Instagram account alongside the caption: "December 15th."
Fans were buzzing that the battle of the online stars has been confirmed, although they were divided about who would reign victorious.
One commented: "KSI finna lose his next fight."
Another wrote: "Speed about to get KO'd in two seconds."
A third added: "Bro is trolling Jake Paul so hard."
A fourth wrote: "If you lose this it will be a meme for years to come."
The announcement comes just days after the results of the appeal that KSI lodged in wake of his fight with Tommy Fury were revealed.
When the Love Island star won on points, he called the result a 'robbery' and vowed to fight the decision.
The sold-out fight took place Manchester's AO Arena on 14 October, with the undefeated British duo battling it out for bragging rights.
The pair were pretty equally matched, with viewers of the fight saying it could have easily gone either way, but it was Tyson Fury's little brother that ultimately came out on top.
Following the fight, two judges ruled in favour of Fury with 57-56, while Rafael Ramos scored the fight 57-57.
However, an error was later spotted on Ramos' scorecard, which was later changed to 57-56, meaning Fury should have technically won by unanimous decision.
But the YouTuber's appeal didn't go the way he hoped, with the Professional Boxing Association releasing an official statement reading: "The PBA confirms that an independent review panel, consisting of two of the country’s leading King’s Counsel and a third lawyer, has determined that there are no grounds to overturn the KSI vs Tommy Fury fight result from October 14, 2023."
You'd think that would be the end of it, but apparently not.
Following their appeal being rejected, KSI's manager and Misfits Boxing chief Mams Taylor said: "The appeals process against the result of KSI's contest with Tommy Fury at the Prime Card, in Manchester on October 14, is ongoing.
"We will now move to the second of three possible stages of the appeal, as we continue to fight to have the decision of the bout rightly overturned."
He later followed that up with: "I don’t give a f**k if it’s a close fight. If it’s the wrong decision, it’s the wrong decision."
Let's hope he doesn't have a similar situation with Speed.Featured Image Credit: Instagram/@KSI/Matt McNulty/Getty Images
