Despite Funaki's body being very broken down from injuries, he returned for a fight against the legendary Rickson Gracie at Colosseum 2000 held at the Tokyo Dome. The show was almost canceled due to Rickson trying to change the rules to make knees and strikes to the head illegal, but the problems were overcome and the show continued. The event was broadcast to 30 million TV Tokyo viewers. There was no championship title at stake and Rickson got the majority of his demands, with elbows and knees to the head being rendered illegal standing or on the ground.
