After 1980, Urquidez' ring appearances became less frequent. Between 1981 and 1984 he fought only sporadically. In 1984, he fought Ivan Sprang in Amsterdam under modified Muay Thai rules (no elbows), winning by 6th-round TKO. His ring career largely came to a halt after 1985, and he retired after facing Yoshihisa Tagami at the age of 41. Subsequently, Urquidez became devoted to acting, teaching kickboxing and martial arts choreography. Urquidez's late brother Reuben was also a competitive martial artist and actor; they appeared together in a 1982 training video, "World Of Martial Arts", along with Steve Sanders (karate), Chuck Norris and John Saxon. Van Halen lead singer David Lee Roth dedicated the band's hit 1984 song "Jump" to Urquidez, of whom Roth was a student.
