Promoter Warren called Usyk's fight with Fury the biggest boxing event of the century

"This is the biggest boxing event of the 21st century. History is being written right now. There hasn't been an outright heavyweight champion in this century - there are four belts at stake instead of three in the last century. These are two undefeated fighters at the peak of their careers. They're in their 30s, and one of them needs to lose a zero in the loss column. On Saturday, we'll find out who the biggest, toughest man on the planet is. Anything can happen in boxing, but I believe Tyson will win and stop Usyk in an exciting fight," Warren said.
