General regulations agreed upon were:  McNichols Sports Arena in Denver, a place which elevation above sea level is one-mile high, has been chosen because Colorado had no athletic commission and thus no governing body from which they would need to get approval for bare-knuckle fighting. The arena hosted only two fight cards in its history, both of minor significance, occurring earlier in 1993. The major accomplishment though for the promoters was to gather a celebrity commentary team for the event. The commentary team for the pay-per-view was Bill Wallace, Jim Brown, and Kathy Long, with additional analysis from Rod Machado and post-fight interviews by Brian Kilmeade. The ring announcer was Rich Goins. Jason DeLucia was an alternate for the event, having defeated Trent Jenkins in the alternate bout. However, as no fighter pulled out during the tournament, he was not called upon. The tournament featured fights with no weight classes, rounds, or judges. The three rules, no biting, no eye gouging, and no groin shots were to be enforced only by a $1,500 fine. The match only ended by submission, knockout, or the fighter's corner throwing in the towel. Gloves were allowed, as Art Jimmerson showed in his quarterfinal bout against Royce Gracie, which he fought with one boxing glove. Royce Gracie won the tournament by defeating Gerard Gordeau via submission due to a rear naked choke. The referees for "UFC 1" were João Alberto Barreto and Hélio Vigio, two veteran vale tudo referees from Brazil. The event and its outcome catapulted Gracie Jiu-Jitsu to new heights in the United States and worldwide. Its gate and PPV buys ensured that there would be more UFCs in the near future, which proved to be the case.
