South African boxer Simiso Buthelezi has died after a WBF African lightweight title fight against Siphesihle Mntungwa on Sunday. He was 4 years old.
Video from the 10th round of the bout went viral on Twitter over the weekend. After having Mntungwa up against the ropes, Buthelezi began aimlessly punching away from his opponent and toward one of the corners of the ring. He later collapsed in the ring, and was rushed to the hospital, where it was discovered that he had a brain bleed.
Buthelezi was placed into a medically induced coma. He died on Tuesday, Boxing South Africa confirmed in a statement.
