Tyson Fury's father John Fury was left with a nasty cut on his face after appearing to headbutt a member of Oleksandr Usyk's entourage at a pre-fight media day on Monday.

WBC belt-holder Fury will face Usyk for the undisputed world heavyweight title in Riyadh, Saudi Arabia on Saturday, with both men defending undefeated professional records.

With both fighters and their camps present at a hotel in the city for media duties on Monday, the build-up to their bout – the most eagerly anticipated in the heavyweight division in recent years – got off to a chaotic start.

Fury's father was pictured with blood running down his forehead after becoming involved in an altercation with a man wearing a Team Usyk tracksuit.

Widely shared footage on social media appeared to show him headbutting the man, who then had to be restrained by other members of Usyk's entourage.

It was later reported that the Saudi Arabian authorities were aware of the incident but did not plan to take any action.
