SEOUL, South Korea — A South Korean boxer who lost consciousness after winning an WBO intercontinental flyweight bout last week has been declared brain dead.

Choi Yoi-Sam was declared brain dead Wednesday, said Ko Seung-kwan, a spokesman at Asan Medical Center. Choi had been in a coma since shortly after winning the fight against Indonesian challenger Heri Amol in Seoul on Dec. 25.

Doctors were scheduled to remove Choi's organs for transplantation after getting approval from the prosecutors' office, a legal requirement before organs can be removed, said Ko. South Korean media reported that Choi had said he would donate his organs.
