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.

McCarthy would often start matches by saying "let's get it on" to the fighters, this became an iconic catchphrase that is associated with him and his refereeing.
