Chuvalo was a five-time Canadian Heavyweight Champion, whose main claim to fame today is that he was never knocked down in his ninety-three professional fights. Chuvalo kept his streak of staying upright intact during his bout against Ali, but he lost a unanimous twelve-round decision. This was Chuvalo's second loss to Ali, with the first having taken place in 1966. Following that first bout, which also ended in a unanimous-decision win for Ali, Chuvalo was described by Ali as "the toughest guy I ever fought."
