After graduation from Korea National Sport University in 2001, he continued to train with the KRA Judo Team. He moved up in weight to the 66 kg class, and won a gold medal at the 2003 Asian Judo Championships in Jeju. However, Jung failed to qualify for the 2004 Olympic Games by losing to Bang Gui-Man in the national qualification match.
Mixed martial arts careerEdit
Jung made his MMA debut on 31 December 2007 against Japanese grappler Shinya Aoki at Yarennoka!. Jung was replacing American Top Team's Gesias Calvancanti, who tore a ligament in his left knee while training to fight Aoki. Although Jung lost by unanimous decision, he proved to be a formidable opponent in his mixed martial arts debut.
