What does KSI stand for and what is Tommy Fury opponent's full name?

KSI puts his unbeaten record on the line this weekend when he faces-off against Tommy Fury.

The YouTube star has branched out into various avenues since beginning posting on the platform in 2008, with his professional boxing career kicking-off in 2019 with a high-profile bout against Logan Paul.

Victories against Swarmz, Luis Alcaraz Pineda and FaZe Temperrr followed, before a no contest clash with Joe Fournier in May of this year - after which Fury called-out KSI to tee-up this weekend’s clash.

Their meeting is expected to be watched by millions, with KSI set to sport the 'world's most expensive mouthguard', worth around £41,000.

KSI’s full name is Olajide Olayinka Williams Olatunji. He is also sometimes known as ‘JJ’, but professionally is known as KSI.

‘JJ’ stands for Jide Junior - in an homage to KSI’s father, who is known as Jide Olatunji. KSI’s first YouTube account used the username ‘JideJunior’.

KSI stands for Knowledge, Strength, Integrity. Explaining the origin of the name in an interview with SportsBible, he said: “KSI actually came from a Halo clan, so this Halo clan called ‘KSI.’

“I, as a kid, really wanted to join the clan, so my name was just Olajidebt on the Xbox 360.

“I remember going to this chat and being like, ‘Oh, I want to be part of the KSI clan.’ And they were like, ‘Ah, okay, you’re gonna have to change your name to KSI Olajidebt,’ blah, blah, blah.

“I said, ‘All right, cool, I’ve changed it, oh my God, am I part of the clan?’ And they were like, ‘Yeah, welcome.’"

KSI takes on Tommy Fury at the AO Arena in Manchester on Saturday, October 14th as he hopes to cause an upset. Logan Paul will also be fighting against
