Pro Wrestling Fujiwara Gumi
Smith had his first contact with mixed rules of fight, when he was invited in November 1989 by the Japanese professional wrestling promotion UWF Newborn. He was scheduled to face up-and-coming wrestler Masakatsu Funaki in a mixed rules fight, but his opponent got injured and was replaced with training partner Minoru Suzuki. During the fight, Smith kept negating Suzuki's takedown attempts by employing the pro wrestling-ruled rope scapes and a rudimentary sprawl ability, knocking him out several times with strike before finishing him with a right punch at the fourth round. The event sold out the Tokyo Dome and broke record gates. On October 4, 1992, Smith would face Funaki in an exhibition fight for Pro Wrestling Fujiwara Gumi, ending in a draw.
