John Fury: Blood flows as Tyson Fury's father headbutts Oleksandr Usyk's team member

Days before Tyson Fury and Oleksandr Usyk engaged in combat, John Fury, Tyson's father, was left bleeding from a fight.

This Saturday in Saudi Arabia, heavyweight champions Fury and Usyk will square off for all four titles.

The fight, which was originally slated for February, was rescheduled for May because Fury cut himself during a sparring session.

A day after Usyk entered the kingdom, hostilities broke out when one of his squad members got into a fight with John Fury, Fury's father.

Several influential members were in Riyadh during the media day for battle week and heard yelling between the two groups.

A member of Team Usyk is seen confronting John in a video that was taken, with each squad leading cries of "Fury" and "Usyk" in turn.

Blood is said to have flowed down John's forehead after he struck one of Usyk's crew members with his head.

The victor of the bout on Saturday will hold all four heavyweight belts, making him the first man to do so since Lennox Lewis.

Twenty-five years ago, in 1999, The Boxer accomplished this feat; this time, four belts are on the line.

This week, reports surfaced indicating that Fury will take home a cool $150 million (£116 million) after the bout.

However, there is rumored to be a condition in the contract requiring the Gypsy King to give £1 million of his revenues to Ukraine in the midst of its conflict with Russia.
