Refereed by John McCarthy

Renowned mixed martial arts referee "Big" John McCarthy is easily the most recognizable, beloved, and by many measures the most experienced referee in professional cagefighting. His resume stretches all the way back to March 11, 1994, where at UFC 2: No Way Out, he served as the lone referee for every single bout on the sixteen man, single-elimination card eventually won by defending champ Royce Gracie. In a time in which "no-holds-barred" fighting's defined ruleset was (by definition) virtually nonexistent, no judges or athletic comissions presided over the events, and the borders between entertainment and chaos in the cage were fuzzy at best, Big John served as the original peacemaker and arbiter of last resort, and his decisiveness, "take charge" attitude and early knowledge of submission holds played a major role in maintaining MMA's tenuous claim to sporting legitimacy.

"Big" John's trademark proclamation at the beginning of each bout: "[Fighter 1], are you ready? [Fighter 2], are you ready? Let's get it on!" has always been synonymous with the nervous buzz of excitement just before a big UFC fight, even during a period from December 2007 through August 2010 in which McCarthy was temporarily estranged from the sport's biggest promotion. Much like boxing ring announcer Michael Buffer, who carried his trademark "Let's get ready to ruuuuumble!" fight call with him across various promotions, "Big" John's "Let's get it on!" is used by him and him alone.

Born October 12, 1962, McCarthy was ably suited to the role of referee when the UFC began airing fights in the early 1990s. He had been a police officer with the Los Angelese Police Department since 1985, and held a Tactics & Self-Defense Instruction Certification that he earned in 1993. He was also a practicing martial artist, and one of the few individuals outside the Gracie family familiar with the art of Brazilian Jiu-Jitsu (McCarthy was awarded his black belt in BJJ in January 2007). Finally, he stood an imposing 6'4" and 240 lbs., important for keeping order in the UFC's rough-and-tumble infancy. From the early goings, his judgments were decisive and generally correct in the cage. He was able to identify threats from today's most recognizable Brazilian Jiu-Jitsu finishes, including triangle chokes and armbars, at a time when most of the audience and announcers could not.

Perennially one of the most sought-after autographs in MMA, McCarthy is the first MMA referee to experience legitimate crossover success as a television and cultural personality and general ambassador of the sport. In addition to officiating bouts for Affliction, Impact FC and Strikeforce, McCarthy held announcing duties for Affliction and did television work for Canada's Fight Network. He played a major role in drafting the modern day Unified Rules of Combat and helped facilitate their passage in a majority of U.S. states. He is a multiple-time speaker at the national Association of Boxing Comissions, where he has argued eloquently for the acceptance of MMA as a legitimate sport, and teaches seminars for the International Professional Ring Officials Association (IPRO). As a side note, McCarthy was also allegedly approached more than a decade ago by officials from Japan's Pride Fighting Championships, then the biggest MMA promotion in the world, and offered a contract to fight under the promotion in a "worked" match, allegedly to be held against Japan's Nobuhiko Takada. McCarthy turned the offer down.

"Big" John McCarthy continues to referee for the UFC and other promotions to this day, and despite refereeing more UFC title bouts than any other referee by far, has maintained a reputation admirably free from controversy over his decisions in the cage.
