talkSPORT presenters Andy Goldstein and Darren Bent were left stunned when John Fury’s outburst knocked them off the air.
Fury Sr stole the show at the press conference to announce KSI’s fight with his son, Tommy when launched tables into the air and had security scrambling to restore order.
It started when co-headliner Logan Paul brought a cake of Dilllon Danis on stage that led to insults being traded.
Fury and KSI then got involved, before it all got too much for John, who proclaimed: “I’ll fight any man in the building.
“Take the cake and stick it up you’re a***. All these f***ing little kids.
“I’m a f***ing machine! Can anyone question who I am here?”
After flipping a table, Fury kicked out at the one that KSI was sitting at, leading to an angry response from the YouTuber-turned-boxer.
Not long before this at 4pm, Drive, talkSPORT’s afternoon show that was broadcasting from the event, was dramatically interrupted albeit for a matter of seconds.
Trying to make sense of what happened, Goldstein told listeners and YouTube viewers: “We’re live from Wembley Arena – I say ahead of the Tommy Fury vs KSI press conference, it’s happening now,” as everything kicked off behind him.
“Apologies that you may have lost us. We ran into a few technical difficulties but I can tell you that the press conference was in full flow behind me.
“I think I’m right in saying that Tommy Fury’s dad, John Fury, took to the stage and then, quite literally, all hell broke loose.
“Tables went up in the air, chairs went up in the air and there was lots of pushing and shoving.”
After such chaotic scenes, Fury Sr took to Instagram on Wednesday to apologise, saying: “Good morning people, I just want to make a quick apology for my inappropriate language yesterday.
“It was unacceptable, I accept that.
“Emotions run high, we get involved and it is the fight game, it was pandemonium.
“But let me sincerely apologise for my outburst of language.
“I wasn’t alone in doing it, but I wanna come out and apologise because I feel it’s appropriate to make that apology to the people who came to the press conference and the viewing audience.
“I sincerely apologise and I’ll try and improve, but people this is John Fury, this is my character, this is who I am.
“I’m a real person, I’m not a fake person, nothing’s scripted, it just happens when it happens.
“But again, I apologise for my inappropriate language and if I’ve offended anybody I’m deeply sorry.
“See you next time.”
