Pro Career

Choi turned pro in 1993 and won the WBC light flyweight title in 1999 with a decision win over Saman Sorjaturong. He defended the title three times before losing it to Jorge Arce by 6th round technical knockout in 2002. In 2003, he lost a decision to Beibis Mendoza for the Interim WBA light flyweight title. In 2004, he moved up in weight to take on Lorenzo Parra for the WBA flyweight title and lost a decision.


On December 25, 2007, he successfully defended the WBO Inter-Continental flyweight title with an unanimous decision victory over Heri Amol. In the 12th round, Choi was dropped with five seconds remaining, but beat the count and went on to win the fight. He collapsed while still in the ring after the bout and was rushed to the Soonchunhyang University Hospital immediately after the fight and underwent emergency brain surgery. Choi died on January 2, 2008, when he was removed from a ventilator after being pronounced brain-dead.
