The rugby world has been shaken by the sobering news that Billy Guyton, a former professional rugby union player for New Zealand, has been posthumously diagnosed with chronic traumatic encephalopathy (CTE). This marks a poignant moment in sports history, as Guyton becomes the first confirmed case of CTE in a fully professional rugby union player from New Zealand, raising serious concerns about the long-term impacts of head injuries in contact sports.
Billy Guyton’s legacy as a scrum-half for the Māori All Blacks and his time with Super Rugby teams such as the Blues, Hurricanes, and Crusaders, was tragically cut short when he passed away at the age of 33. His family’s decision to donate his brain to the University of Auckland’s brain bank has led to a groundbreaking discovery that underscores the risks associated with the sport he loved.
The diagnosis, confirmed by Associate Professor Michael Buckland, founder and director of the Australian Sports Brain Bank, revealed stage 2 CTE in Guyton’s brain. This level of the disease is considered moderate, situated between the mild and severe stages. The findings have sparked a conversation about the early onset of brain damage due to head knocks, as highlighted by Prof Maurice Curtis, co-director of the Auckland brain bank.
Guyton’s premature retirement in 2018 at 28, due to the debilitating symptoms of multiple concussions, now takes on a new significance. The report detailing his condition also noted a cavum septum pellucidum, a brain fissure linked to traumatic brain injury, and age-related tau deposits, which, while not diagnostic of CTE, are often associated with it and unusual in a young brain.
New Zealand Rugby has expressed deep concern over the loss of Guyton and the implications his diagnosis may have for the sport. The organization is taking steps to mitigate the risks of head impacts, including the introduction of smart mouthguards and lower tackle heights, among other initiatives. However, the reality remains that CTE can only be diagnosed after death, leaving many unanswered questions about the long-term brain health of current and former players.
The case has also cast a spotlight on the legal actions being taken by former professional rugby players against governing bodies like World Rugby, the Rugby Football Union, and the Welsh Rugby Union. These players allege that they were not properly cared for or informed about the risks of repeated head injuries during their careers.
While the rugby community grapples with the implications of Guyton’s diagnosis, it is clear that the sport is at a crossroads. With the potential for many more players to be diagnosed with CTE postmortem in the coming years, there is an urgent call for the sport to address the amount of contact players endure throughout their careers. The safety of the brain must be a priority if the sport is to protect its athletes and ensure its future.
In memory of Billy Guyton, the rugby world must now tackle the challenge of balancing the physical nature of the sport with the health and well-being of its players. It’s a difficult conversation, but one that is necessary to honor the legacy of those who have given so much to the game.
