John Michael McCarthy (born October 12, 1962) is a retiredAmericanmixed martial artsreferee best known for officiating numerous bouts promoted by the Ultimate Fighting Championship (UFC), dating back to UFC 2.[1] He is credited as being one of the greatest and most recognizable referees in combat sports history and an important figure in the mixed martial arts world, helping create the Unified Rules of MMA after initially creating the original rule book of the UFC. He is currently a commentator for Bellator MMA and co-hosts the combat sports-based podcast "Weighing In" with former fighter Josh Thomson.[2][3]
In 1993, he became involved with the newly created Ultimate Fighting Championship (UFC) fighting tournament. He was the referee for UFC 2, launching a career as a UFC referee. The UFC initially started with very few rules, but McCarthy gave feedback that it was too dangerous and suggested additional rules, many of which were adopted. McCarthy would often start matches by saying "let's get it on" to the fighters, which became an iconic catchphrase that is associated with him and his refereeing.[4]
The nickname of "Big John" came about because of his size and stature. He stands 6 ft 3 in (1.91 m) and weighs 265 lb (120 kg); making him larger than the majority of the athletes over whom he presides. According to a UFC interview, the nickname was given to him by UFC co-founder and promoter Art Davie. McCarthy recalls that the nickname began when he forcibly lifted Davie off the ground and held him in the air.[5]
In 2018, McCarthy retired from UFC refereeing, and moved to Bellator as a commentator.[6]
