Hibikiryu, 28, landed on his head during a bout in March and was later treated for a spinal injury
A Japanese sumo wrestler has died a month after suffering a concussion during a bout, as the ancient sport’s authorities come under renewed pressure to rethink their outdated approach to head injuries.
Hibikiryu, a 28-year-old rikishi in one of the lower divisions, died from acute respiratory failure, the Japan Sumo Association said, despite earlier showing signs that he was recovering from his injuries.
