Dhaka, Aug. 10 -- Two Japanese boxers lost their lives from brain injuries sustained in separate matches held on the same event at Tokyo's Korakuen Hall.

Shigetoshi Kotari, 28, collapsed shortly after completing a 12-round draw against Oriental and Pacific Boxing Federation junior lightweight champion Yamato Hata on August 2. He underwent emergency brain surgery for a subdural hematoma-a condition where blood pools between the brain and skull-but passed away on Friday.

The World Boxing Organization (WBO) expressed condolences on social media: "Rest in peace, Shigetoshi Kotari. The boxing world mourns the tragic loss of this warrior and sends thoughts and prayers to his family, team, and the Japanese boxing community."
