John Fury explains why he got in fight with member of Usyk's team after alleged headbutt

There's a few things you can count on in life - death, taxes and Big John Fury causing absolute murders before one of his sons faces the biggest fight of their life.

We've seen him headbutt a plastic screen separating him and KSI before Tommy stepped into the ring, throw water bottles and flip tables, publicly pull a mooney... and that's just in the last few months.

Now, ahead of Tyson's highly-anticipated clash with Oleksandr Usyk on Saturday (18 May) in Saudi Arabia, the dad has caused chaos by allegedly using his noggin to remind a member of the Ukrainian boxer's team who they're dealing with.

Videos of a supposed ruckus between the two camps have gone viral online, which appears to show both sides shouting at each other before John goes head-to-head with one of Usyk's companions.

There's a clear divide in the crowd as one side is yelling 'Fury' and the other 'Usyk' at the top of their lungs, until tensions apparently spilled over.

John is alleged to have delivered one of his trademark headbutts to a member of Usyk’s entourage, Stanislav Stepchuk.

Reports claim that Tyson, who had been in a side room doing an interview, emerged to see his dad with a bloody forehead before asking: "What’s happened to your head, you silly c***?"

Security are said to have then intervened in the incident, which has sparked outrage ahead of the Gypsy King's clash against Usyk - which was initially supposed to take place in February, before it was postponed.

According to the bloke who is claimed to have been headbutted, Stanislav, he was 'simply supporting his team' and claimed he was only chanting Usyk's name.

He told Seconds Out: "I didn't touch him. He went crazy… Yeah [I wanted to punch him], but because of the age difference it would not be very fair.

“He should not look for an actual fight because he could have a heart attack and finish in the ambulance."

John has also since offered up his side of the story, claiming that Tyson's opponents entourage were taunting him.

During an interview with Sky Sports - while still sporting a splodge of blood on his head - the patriarch of the Fury clan said: "Disrespecting my son, the best heavyweight to ever wear a pair of boxing gloves. Coming out with all that rubbish.

"You know he's [Stanislav] in my face, trying to be clever. Coming into my space, 'Usyk, Usyk!'

"Nobody's bothering with them. I was only chanting my own son's name! So they stepped closer and stepped closer. So at the end of the day, I'm a warrior, that's what we do."

John took the opportunity to remind boxing fans that settling an issue with fisticuffs is in his blood, as he routinely boasts that he comes from a long line of bare-knuckle fighters, while also having 13 professional fights to his name himself.

He continued: "We're fighting people. You come in the space, you've got to get what's coming.

"Listen, it's not about the fight," he said.

"We've done everything we can, Tyson's in fine fettle. You're probably going to see on Saturday night the best Tyson ever. But this is what he comes off, we're fighting people.

"That there, is a regular occurrence, seven nights a week for me that. We're not interested.

"So the last thing they're going to do, is get one over on me or my family. it will not happen. You be disrespectful - we don't talk, we don't scream," he said, before smacking his hands together.

"Who cares? Not me," John added, before he began chanting his surname on repeat.

Luckily for those who are fans of seeing the Fury family draw blood, you can catch Tyson taking on Uysk at the Kingdom Arena on Saturday at 11pm UK time, while the weigh-in is on Friday at 7pm.
