Big John Fury erupts during KSI and Tommy's press conference and destroys everything in sight

Tommy and Tyson Fury's dad, Big John Fury, got a head start on the violence as he destroyed the stage when he showed up to support his son ahead of his fight with KSI.

Check out his rampage below:

Fury, who is now 59-years-old, was at the event to support his son, but he made clear that he wasn't too happy when KSI accused his other son, Tyson Fury, of avoiding WBA, WBO and IBF title holder Oleksandr Usyk.

After shouting and smashing his hand on the table, Fury began to destroy the stage as he threw water bottles, and tipped and kicked tables.

Other people on the stage soon got involved in the brawl, and before long Tommy and KSI jumped up to join in the chaos.

KSI has previously made clear he's extremely confident that he'll take the win in the fight, telling DAZN that he couldn't wait to 'destroy' Tommy.

“A YouTuber is going to knock out Tommy Fury and there’s nothing you can do about it,” he continued.

"Tommy Fury is the boxer, obviously he’s the man everyone thinks is going to beat me but it’s actually up to me [when the fight ends], I’m the one that decides.

“And when I have you in the ring Tommy Fury, when I grab your big, fat head and constantly hit you with that right hand, it’s night-night buddy and your legacy is done.

“I will be the ultimate crossover boxing champion of all time!”

Tommy, however, wasn't so sure.

After hearing KSI's comments, the boxer tweeted: “KSI I’m deep in training camp whilst you’re making a fool out of yourself at fights. Keep talking s***….come the 14th I’m going to destroy you.”

The crossover event is set to get underway at 7pm UK time on 14 October.
