UFC 3 used an eight-man tournament format, with the winner receiving $60,000. The tournament had no weight classes or weight limits. Each match had no time limit or rounds; therefore no judges were used for the night. Competitors could only win a match by submission, throwing in the towel, knockout, or referee stoppage. This event marked the first time the referee was given the authority to stop the contest. The referee for the night was once again "Big" John McCarthy.
