Boxing South Africa (BSA) announced that Simiso Buthelezi died Tuesday due to internal bleeding from a brain injury incurred during his WBF All Africa title bout Sunday against Siphesihle Mntungwa in Durban, South Africa.
The fight ended in bizarre fashion. After leading through ten rounds Buthelezi forced Mntungwa back to, and through, the ropes.
After the referee stepped in to restart the action, it became clear that Buthelezi—who was caught by Mntungwa coming in—was not aware of what was happening around him. The fighter can be seen turning towards the referee, adopting his fighting stance, and then advancing into an empty corner where he starts to throw punches.
