The Indonesian government has ordered an investigation into the death of a boxer, Muhammad Afrizal.
The 30-year-old died of head injuries after a professional fight.
Afrizal died of a brain hemorrhage on Wednesday after a featherweight fight last weekend. He was due to be married on April 15.
"Boxing is an extreme sport, that's why all the rules must be strictly applied," sports minister Andi Mallarangeng said on Thursday.
"I have ordered BOPI (the professional sports body) to investigate whether all rules were properly applied during the fight."
Indonesian boxing commission chairman Anton Sihombing said that no rules were broken during the 12-round bout in Jakarta between Afrizal and Irvan Marbun, who was declared the winner.
"Everything had gone well. No rules were violated. We followed all the required procedures, including a health check before the fight," he said.
Reporters said Afrizal showed signs that he could not finish the fight after the eighth round and the referee should have stopped the bout. Sihombing denied it.
"He kept kicking until the end of the 12th round. The referee can't take any action unless the boxer falls down three times in a row," he said.
Afrizal vomited an hour after the fight and the next morning underwent brain surgery, Sihombing said.
"I met his family and fiancée,” he added. "They told me they had just finished sending the wedding invitations when he died."
