Answer by taking a quote from the following article:

Williams attended Lakewood High School in Colorado, graduating in 1978. He was on the track & field team, played football, and wrestled all four years. Williams graduated from the University of Oklahoma in 1981 after a football career that saw him named an All-American. He also competed as an amateur wrestler, where he was a four time

In 1998, Williams was signed by the World Wrestling Federation (WWF) prior to the "Brawl for All" competition which was set up in legitimate fights. He entered the competition and was expected to win it due to his reputation as one of the toughest men in the wrestling business. However, after beating Pierre Carl Ouellet in the first round, he faced Bart Gunn in the semifinals and suffered a torn hamstring. Gunn then knocked out Williams, who missed several months following the injury. Following the event, Williams was involved in a brief angle where he was managed by Jim Ross in early 1999 before Williams was released. During his time with Ross, he would attack people with suplexes. Jim Cornette later said that because of how his WWF career had gone he had legitimate bad feelings toward his longtime friend Ross, whom he blamed for the entire thing; Williams was being groomed by Vince McMahon as a possible contender for the WWF Championship that was in the possession of Stone Cold Steve Austin during the Brawl for All tournament. In 1999, Williams appeared briefly in World Championship Wrestling (WCW) again, with Oklahoma as his manager in a feud with Vampiro, as a result of this feud, he wrestled against Jerry Only from the Misfits on the November 29, 1999, edition of WCW Monday Nitro in a steel cage match. He went back to All Japan Pro Wrestling in 2002 and wrestled a couple of matches for WWE in 2003 against Lance Storm. In late 2003, he was involved with the independent promotion Major League Wrestling (MLW) and also wrestled for the new NWA Mid-Atlantic, where he won their title in one of the first professional wrestling events in China. On March 14, 2004, Williams faced Belarusian kickboxer Alexey Ignashov in a mixed martial arts bout in the K-1 promotion and was knocked out 22 seconds into the fight. This proved to be his first and only professional fight.
