Helio Gracie x Yukio Kato
Helio sent a challenge to some Japanese judokas which included Yamaguchi, Kato and Kimura. Yukio Kato, 5th degree black belt was the first. In september of 1951 happened the first fight of the athletes, which was very tough and ended in a draw after three rounds. Helio demanded another fight which happened three weeks later in 29 of september 1951. At the second match, which lasted several minutes, a key element happened: Kato had applied several takedowns and tried to submit Helio. Both fighters were at the end of the ring, which made the referee ask the match to stop to drag the fighters to the center. During this time, Helio applied a choke and Kato passed out. The infraction wasn’t counted and Helio was declared the winner.
