Light heavyweight prospect Tommy Fury has vowed to end the boxing run of social media star KSI.

Earlier this year, Fury picked up an upset decision win over Youtube star turned boxer, Jake Paul, who tasted defeat for the first time as a pro.

On Saturday night, Fury was ringside at the OVO Arena Wembley, as he watched KSI score a controversial two round stoppage of unbeaten pro boxer Joe Fournier in a non-sanctioned fight.

Fournier (9-0, 9 KOs), 40-years-old, had a very inflated record against very limited opposition.

The contest came to a close in the second, when KSI blasted Fournier out with an elbow to the jaw. The referee missed the illegal blow and waved off the fight as Fournier was down and seriously hurt.

After the fight, KSI and Fury came face to face - and a heated war of words would lead to a scuffle.

Fury vowed to eliminate KSI within four rounds - and also put KSI's promotional company Misfits Boxing to an end.

"All I can say is, sign me up. Easy money, [KSI is] easy money. You are going to sleep in four rounds. Four rounds, asleep. Gung ho, no defense, no head movement. Knocked out," Fury said.

"Guess what? You didn't beat a pro boxer tonight, I'm the pro boxer, let's get that straight. I've already ticked off one name in Jake Paul, he's done, he's finished and you will be ticked off. Like it or not you will be ticked off and Misfits is going to be over."

KSI, who is quickly running out of opponents to face on pay-per-view, is practically begging for the fight to take place.

"I'm annoyed at Tommy Fury man, that guy pissed me off, he's a d!ckhead. Let's get that contract sorted, man.  I need Tommy Fury," KSI said.

"I truly believe I can knock him out, get my timing on him and sleep him. My power is not like Jake's it's more, it's devastating.  It's different. He said I'm easy money, he would destroy me and destroy Misfits.  Nah man. I want to crush and destroy and want to be known as one of the best in this scene. I want the fight this year."
