TYSON FURY’S dad John was left with blood pouring down his forehead as the build up to the undisputed world heavyweight clash with Oleksandr Usyk got off to an explosive start in Riyadh.

The rival camps had to be separated by security at the hotel where today’s media activity was being held.

John was left with a cut from an alleged headbutt, and the blood continued to flow despite the 59-year-old’s attempts to wipe it away. He had to be restrained repeatedly while Usyk’s camp chanted “Usyk, Usyk, Usyk.”
