What stands out in Jamie Cudmore’s story is not just the legal case, but the shift in perspective. A player once seen as the ultimate competitor is now helping lead a harder conversation about how the game has failed to protect its own.

Former Canada international Jamie Cudmore said he had been helping the group of ex-players around Steve Thompson as they prepared legal action connected to rugby’s dementia crisis. He told BBC Sport he had been speaking to them for months, “helping them along the way,” as concern over long-term brain injury in rugby intensified.

“It’s very alarming that now the wider public understand the depth that this problem really does go and how we need to do a hell of a lot better as professional sportsmen, as coaches, administrators, to protect players a lot better.”

Cudmore is suing Clermont Auvergne over their alleged failure to protect him from serious injury when he returned to the pitch after suspected concussions during the 2015 Champions Cup, after playing for the club from 2005 to 2016. A court-appointed neurologist found in 2019 that the club was responsible for the harm he suffered, making the case potentially significant for the wider sport.

He said the case was “not a money grab” and described it instead as a chance to draw a “line in the sand” around education, accountability, and better treatment of head injuries in rugby.

That message lands even harder when set against how elite sport has often treated head trauma differently from visible physical injuries. Cudmore’s account reinforces the idea that brain injury must be treated immediately and decisively, not debated in the moment because the player still wants to compete.

“In this day and age, if you do that with a young child you can kill them... nobody should get to that point in their sporting careers and be that injured by someone’s negligence.”

BBC Sport also reported that the broader player group around Steve Thompson involved former professionals diagnosed with early signs of dementia and preparing negligence claims against governing bodies, with concerns that repeated concussive and sub-concussive blows had left permanent damage.

Cudmore’s position now is simple: rugby remains a contact sport, but concussion treatment has to improve dramatically. That same principle runs through the work around HIT — if the brain may be injured, the response cannot wait for visible proof.
