Mixed martial arts career
Jennum entered the UFC 3 tournament as an alternate. Ken Shamrock made it to the finals of UFC 3 but withdrew. Jennum then stepped in as a replacement and subsequently won his fight, winning the tournament. Therefore, Jennum only needed one fight to win the UFC 3 tournament (normally a fighter would have had to participate in three matches to win). This anomaly prompted the UFC to change its rules, requiring alternates to win a preliminary fight to balance the advantage of being an alternate.
After UFC 3, Steve Jennum would go on to win only one more fight in his career, defeating Melton Bowen in UFC 4, who was 31-6 as a professional boxer going into the bout. Jennum performed a high profile O goshi hip throw on the boxer, much to the delight of the crowd, eventually forcing him to submit to a straight armbar. Jennum could not continue in UFC 4 due to swelling of his hands after hitting Bowen repeatedly in the head when Jennum was on full mount.
Prior to his debut in the ring, Jennum was a high ranking Black Belt Instructor in Robert Bussey's Warrior International (RBWI). Jennum also started his own martial arts school in Omaha, NE. UFC welterweight champion Georges St. Pierre mentioned that watching Jennum win UFC 3 contributed to his decision to compete in mixed martial arts.
