Former All Black Sonny Bill Williams, speaking from hospital before his recent neck surgery, issued a stark warning to young athletes and parents about the enduring physical toll of professional sport. The professional boxer and retired dual-code international player, preparing for his fourth neck operation, noted that health consequences often persist after a playing career ends. While he expressed no regrets, acknowledging that rugby provides income, identity, opportunity, community and pride, he stated that no organisations were checking on him or paying his bills for health issues stemming from his playing days. His comments spotlight a question sport has yet to resolve: who bears the cost when an athlete's body continues to pay after the final whistle?
The Health Cost of Playing Rugby
Concussion typically dominates discussions about long-term player welfare, and for good reason—concerns about repeated head impacts have reshaped rugby's safety debates. However, concussion is only part of a broader picture. Retired athletes also contend with osteoarthritis, chronic pain, reduced mobility, hip replacements, back pain, mental health challenges, and loss of identity following an elite career. Research indicates these problems are widespread. A New Zealand Rugby health study found former rugby players reported more serious injuries, higher rates of osteoarthritis, and higher levels of hazardous alcohol use compared to former non-contact sport players. International studies corroborate these findings: a scoping review revealed retired male elite rugby players had higher prevalence of osteoarthritis, mild cognitive disorders, depression, and hazardous alcohol use than control groups. A 2025 study also found that each previous shoulder or knee surgery was associated with roughly double the odds of osteoarthritis in that joint later in life.
Mental Adjustments to Sports Retirement
Professional athletes often face psychological challenges after retirement, losing structure, status, income, and a sense of belonging and identity. A recent study of retired elite rugby players found that athletic identity and psychological flexibility were linked to wellbeing after retirement. New Zealand has made some progress: professional players are life members of the Rugby Players Association, receiving support during their careers, overseas, and in long-term retirement. Services include mental wellbeing, career advice, financial education, retirement services, and professional networks. The new 2026–28 agreement between New Zealand Rugby and the Rugby Players Association also expands medical, life, and trauma insurance for players in Super Rugby Aupiki, New Zealand's premier professional women's rugby union. However, gaps remain in helping players with osteoarthritis, chronic pain, repeated surgeries, and mental health challenges that may emerge years after a contract ends.
Getting Cover for Gradual Conditions
The Accident Compensation Corporation (ACC) plays a major role in New Zealand's sport injury system, covering accident-related injuries with treatment, rehabilitation, and financial support. However, ACC does not cover everything. Gradual conditions are harder to cover if treated as age-related, degenerative, pre-existing, or not clearly linked to a covered injury. Some work-related gradual injuries—like tendinitis from heavy lifting or knee osteoarthritis from carpet laying—can be covered, but each claim requires evidence that work tasks or environment caused or contributed to the injury. Private health insurance is not always a fallback; pre-existing conditions are commonly excluded unless cover is specifically agreed. Some policies never cover pre-existing hip, knee, or back issues, nor reconstructive or reparative surgery. This creates a grey zone: a retired player may need surgery or joint replacements linked to years of professional sport, but these may not fit ACC requirements, private insurance, or player-welfare systems.
Ethical Responsibilities of Sport
A recent article develops an ethical framework for asking when society is justified in tolerating foreseeable sport-related harm because sport is considered in the “public interest.” This does not mean athletes should simply accept harm; rather, it asks what responsibilities sport has if it relies on public-interest arguments to accept risks that would be unacceptable in other settings, especially when those risks are known and can affect players long after retirement. Rugby brings people together, and the benefits of professional sport are shared widely. However, the ongoing costs must also be shared. The question is not whether rugby can ever be safe—collision sports always involve risk. A better question asks what long-term player welfare should look like when some risks are foreseeable, repeated, and increasingly well documented. This might mean stronger transition planning, long-term health monitoring, clearer medical support, or case management to help retired players navigate ACC, insurance, and public health systems. Rugby does not need to be risk-free to be ethical. But if the game continues to generate revenue and national pride, it is reasonable to ask what responsibilities remain when the playing days are over. For some athletes, the bill arrives long after retirement.
