Simiso Buthelezi, a South African boxer, has passed away following Sunday's fight against Siphesihle Matungwa. After knocking Mntungwa to the ground, Buthelezi was seen punching aimlessly away from his opponent and kicking off.

Because Buthelezi was clearly having problems, the referee stopped the fight immediately. Mntungwa won via TKO. Buthelezi was taken to King Edward VIII Hospital, where doctors found a brain injury and put him in an induced coma.

Boxing South Africa issued a statement on Wednesday morning confirming Buthelezi’s death.

The statement said that "Boxing South Africa and his family are deeply saddened to announce the death of Mr Simiso Buthelezi last night at Durban Hospital on June 7, 2017." "Towards end of his fight, Mr Buthelezi fell and was taken to hospital. It was found that he had suffered a brain injury that caused internal bleeding. Although Mr Buthelezi received the best medical care, he eventually succumbed to his injuries at the hospital.

Buthelezi entered the WBF African lightweight title bout having a record of 4-1 as a professional. He seemed on track to pick up another win when the injury struck.

Bheki Mngomezulu was Buthelezi’s trainer and said that there wasn't any untoward happening in the fight or in training. He was leading the fight on points prior to the unfortunate incident. To be honest, I don't know how to explain it. Although it was quite bewildering, he was in good health and was well trained for the fight. He was healthy before the fight.

Buthelezi was 24.
