Fans have been left stunned after seeing Vince McMahon arrive at the Kingdom Arena in Riyadh, Saudi Arabia, for Tyson Fury's fight with Francis Ngannou.
A plethora of celebrities and A-listers from various worlds will be in attendance for the heavyweight clash, which is being dubbed 'The Battle of the Baddest' and sees former UFC champion Ngannou make his boxing debut.
