Hayman will spread the word about how the lobby group believe the players and the game can be better protected.
Hayman, 42, is one of a growing number of players that have been diagnosed with early onset dementia and probable chronic traumatic encephalopathy (CTE).
“I met with Progressive Rugby when I was in the UK and it was clear that their only focus is the welfare of the players and the game,” Hayman said.
“They spoke of their determination to protect the game for future generations who they want to gain as much enjoyment from the game as they have. The group’s clarity of purpose and drive was impressive, and I’m delighted to support them.”
Hayman played 46 times for New Zealand, including RWC 2007 and against the British and Irish Lions during their 2005 tour to New Zealand.
Hayman has since revealed that he had been diagnosed with early onset dementia and probable chronic traumatic encephalopathy (CTE).
He has spoken how following his retirment he suffered with ceaseless headaches that sent him into a spiral of alcohol abuse and frequent suicidal thoughts. He is part of the action against World Rugby and the RFU.
Hayman’s primary role will be to spread the word on Progressive Rugby and the requirement plans produced for both the elite and community/youth game. He will also advocate for education and a change in language around brain injury.
