Former WBC light-flyweight champion Choi Yo-sam has died after collapsing during a fight on Christmas Day.
Choi won the WBC light flyweight title in 1999
The South Korean had been defending his WBO intercontinental flyweight title against Indonesia's Heri Amol, who floored Choi at the end of round 12.
Choi returned to his feet and won the bout on points, but was rushed to hospital when he collapsed soon after.
The 33-year-old had suffered cerebral haemorrhage and was pronounced "brain dead" by hospital officials in Seoul.
Choi won the WBC light-flyweight title in 1999 with a points win over Thailand's Saman Sorjaturong.
