5. Gerard Gordeau vs. Teila Tuli
To be fair many of the bouts in the first few UFC events could make this list, but Gerard Gordeau vs Teila Tuli deserves special mention. This was the first UFC fight ever to air on PPV, with neither guy deciding they were going to continue with the sport afterwards.
Tuli was a sumo wrestler and was paired up against a dutch karate champion in Gordeau. As he was used to doing in sumo, Tuli charged at his opponent, only unlike in sumo this time his opponent dodged him. Tuli stumbled and upon getting to his feet was kicked squarely in the face. And with that Tuli’s MMA career was over.
As for Gordeau he made it all the way to the finals that night, only to lose to Royce Gracie. He would only ever compete in one other mixed martial arts event, a losing effort at Vale Tudo Japan 1995.
