The 1990’s were a simpler time. We carried CD Discman’s, watched sitcoms like Full House and Family Matters, and it was fully within the rules (what rules?) of mixed martial arts to pummel the groin of your opponent.

UFC 4 took place on December 16, 1994 at the Expo Center Pavilion in Tulsa, Oklahoma. Although Brazilian jiu-jitsu black belt Royce Gracie would go on to defeat hulking wrestler Dan Severn by triangle choke in the show’s main even, it was the match between Keith Hackney and Joe Son that occurred earlier in the night that would give fans something to talk about for years to come.

Keith Hackney made his Ultimate Fighting Championship debut at UFC 3, where he defeated the enormous sumo wrestler Emanuel Yarbrough. Hackney brought to the cage a background that was especially varied for the time, having studied boxing, wrestling, Taekwondo and Kenpo karate.

Hackney’s opponent, Joe Son, was a practitioner of his own martial arts fighting system known as Joesondo.

At about the 2-minute mark of their UFC scrap, Hackney is able to secure side control, while Son tries to stifle Hackney by grabbing his neck. Unable to immediately free his neck from Son’s grasp, Hackney (who was in the perfect position to do so) delivers several powerful strikes to Son’s family jewels, which was perfectly legal at the time.

Joe Son would tap out moments later, likely due to the kind of pain no man wishes to endure, declaring

Keith Hackney winner by submission.

Joe Son would go on to act in the smash hit motion picture Austin Powers: International Man of Mystery as Random Task, a parody of the James Bond villain Oddjob. He was later convicted of a heinous crime, and then committed murder in jail.

Keith Hackney is a highly respected trainer, who runs Hackney’s Combat Academy in Elmhurst, Illinois.
