Career
The crowning moment in Jeon"s judo career came in winning the gold medal in the men"s middleweight division at the 1996 Olympics in Atlanta, United States. He defeated Armen Bagdasarov of Uzbekistan in the final match by ippon. Jeon retired from competition at a relatively young age of 25 in 1999, citing both knee injuries and an absence of motivation due to lack of competition. He retired undefeated in both Olympic and world championship competition.
In 2003, PRIDE Football Club and Antonio Inoki tried to sign Jeon to fight Yoshida under Mobile Marketing Association rules (using the fact that Jeon have never lost against Yoshida in judo) but Jeon refused offers.
