Shigetoshi Kotari died Friday from a brain injury he suffered during his draw with Yamato Hata on Aug. 2 in Tokyo, according to multiple reports.

Kotari, 28, lost consciousness after the conclusion of the 12-round bout for Hata’s Oriental and Pacific Boxing Federation junior lightweight title and was rushed to a hospital for emergency brain surgery for a subdural hematoma, which is another term for a brain bleed.

Kotari (8-2-2, 5 KOs) and Hata (17-2-1, 16 KOs) fought to a split draw at Korakuen Hall.

Kotari, of Nagoya, had won two consecutive eight-round fights by unanimous decision to earn the title shot against Hata.

“Rest in peace, Shigetoshi Kotari,” the World Boxing Organization wrote on social media. “The boxing world mourns the tragic passing of Japanese fighter Shigetoshi Kotari, who succumbed to injuries sustained during his August 2nd title fight. A warrior in the ring. A fighter in spirit. Gone too soon. Our thoughts and prayers are with his family, team, and the entire Japanese boxing community.”
