KSI, 30, is a YouTube star and rapper who garnered a huge following through his gaming videos. He co-launched Prime energy drinks with fellow YouTuber Logan Paul.

Tommy Fury, 24, is the younger brother of heavyweight world champion Tyson Fury.

He starred on the fifth series of Love Island in 2019, where he met his fiancee Molly-Mae Hague. The pair welcomed their first child Bambi in January.

When and where is the fight?

KSI and Fury are set to face off in a six-round cruiserweight match at Manchester's AO Arena on Saturday 14 October.

Coverage will start at 7pm, with the ringwalk at around 10pm - though this could change depending on the length of the undercard fights.

Who's on the undercard?

The "Prime card" event will also see Logan Paul clash with MMA fighter Dillon Danis.

Danis is Conor McGregor's training partner, who was meant to clash with KSI in January but pulled out.

Paul told Sky News he's been "working out hard six days a week" in preparation for the battle.

Paul - who wants to be a champion in WWE - added: "I don't want to be a professional boxer. I have so many interests and passions that I want to pursue. Boxing's fun. I really like it, I like entertaining...

"This is an amazing opportunity to entertain a lot of people."

Here are the rest of the fights expected on the undercard (which is subject to change).

Salt Papi vs Slim Albaher

Deen the Great vs Walid Sharks

King Kenny vs Anthony Taylor

Whindersson Nunes vs My Mate Nate

Wassabi Lmao (Alex Wassabi & NichLmao) vs Los Pineda Coladas (Luis Alcaraz Pineda & BDave) - tag-team match

Can I buy tickets?

The general sale for tickets to the fight opened on 25 August at 10am, with people trying to buy tickets told to join a queue.

Notices popped up on people's screens telling them they were in a queue of thousands of people.

Prices range from £40 to £2,000 depending on what seat you choose.

But it seemed like general sale tickets sold out pretty quickly, with only the expensive tickets left by the time it hit 11am.

How heavy will the fighters be?

The contracted weight for the Fury v KSI fight is 183lbs, with no rehydration clause - a limit on how much weight a fighter can put back on after weigh-in.

The pair had a public row after KSI accused Fury of trying to raise the weight from 180lbs to 185lbs, before coming to an agreement.

What has each of them said?

At a pre-fight news conference, Fury insisted "YouTube boxing will be done" if he beats KSI.

He also claimed the fight would be "easy money" and he will beat the YouTuber "inside four rounds".

Speaking to Sky News, Fury said he's ready to end YouTube boxing and pursue his dreams of becoming world champion.

"I've beat the best YouTube boxer out there, so this man [KSI] is going to be in serious trouble.

"I'm going to bully him around that ring, there's no way he can escape. And I'm going to finish him whenever I want to finish him.

"But make no mistake, my goal is still to be a world champion, and I will always stay on that path."

Meanwhile, KSI said he will be looking to "silence his doubters" against Fury.

"I came back to boxing to show the world the crazy levels I'm at. I've shown through obliterating all my past opponents that I am the best in this scene."

The fight has not been sanctioned by the British boxing regulator as a professional match - and KSI lacks a professional licence in the UK.

Only one of his previous fights has been professionally sanctioned, with the others all exhibitions.

His bout with Fury has instead been sanctioned by the Professional Boxing Association, but it won't count towards either fighter's professional record.
