Tokyo

Two Japanese boxers have died from brain injuries sustained in separate bouts on the same card 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 Aug. 2.

He underwent emergency brain surgery for a subdural hematoma — a condition where blood collects between the brain and skull – but died on Friday.
