Players in both rugby codes regularly under-reported concussion symptoms and manipulated test results so that they would not be stood down, Hape said. The result was that many ended up suffering further concussions, with devastating consequences.
Hape's memory became so poor he could not remember his PIN number and he was eventually instructed to retire after brain function tests showed he had become seriously impaired. As well as memory loss he has suffered constant migraines, irritability, depression and sensitivity to light and sound.
Former England hooker Brian Moore said Hape's worrying story showed rugby's concussion protocols needed to be changed. A vocal spokesman on concussion issues in rugby, Moore, who is now a broadcaster, believes testing and research should be conducted by independent bodies. "What the @ShontayneHape piece & other research shows is IRB protocol needs amending & above all independent game assessments & research," Moore tweeted.
International Rugby Board chief executive Brett Gosper responded that the IRB was "always assessing, learning, improving protocols. Culture shift needed so players & teams respect real dangers".
Outspoken Samoan international Eliota Fuimaono-Sapolu implored all young rugby players and parents to read Hape's story. "Parents & youth. You have so much information available to you that we never had. MUST READ. Thank u @shontaynehape," Fuimaono-Sapolu advised his 20,000 Twitter followers.
Former Kiwis captain Roy Asotasi, long-serving forward Joe Galuvao, barnstorming prop Hitro Okesene and Warriors fullback Sam Tomkins were among a host of league stars to praise Hape for telling his story.
