Lyndon Byers, the former Boston Bruins enforcer and longtime radio co-host, was posthumously diagnosed with chronic traumatic encephalopathy, his family announced Thursday. Byers, who died last July at 61 years old, had pledged before his death to donate his brain to the UNITE Brain Bank at Boston University’s CTE Center for testing.
The diagnosis, provided by Dr. Ann McKee of the CTE Center, found Byers had Stage 3 of 4 of the progressive, degenerative disease. Dr. McKee said, "With stage 3 disease like Lyndon Byers had, individuals almost always report cognitive symptoms, and 50% develop dementia." Byers’ family authorized the release of the results to raise awareness about the effects of CTE.
Byers played 10 seasons in the NHL, including nine with the Boston Bruins, and finished 11th in franchise history with 959 penalty minutes — numbers that, for some, underline a career spent in the game's most physical moments. Before he died he had also been a longtime co-host on WAAF’s The Hill-Man Morning Show, remaining a familiar voice to local listeners even after his playing days ended.
The family’s announcement arrives amid a stark pattern in research from the Boston University CTE Center and advocacy groups: according to the Concussion & CTE Foundation, 19 of the 20 former NHL players studied at the center were posthumously diagnosed with CTE. Those figures have become central to debates about player safety in contact sports, and the Byers result adds another high-profile example.
The personal toll of the disease was detailed by Byers’ widow, Anne Byers. She said he "became less social toward the end of his life," battled severe depression, "had episodes of hallucinations, and his struggles with short-term memory loss made it difficult for him to navigate the day on his own." In her statement she linked that account to a call for change: "I will do whatever I can to make sure nobody else has to watch their loved one deteriorate like that."
That call frames the tension in this case. The diagnosis confirms the presence of advanced disease in a former player, while the larger clinical picture — that half of people with stage 3 progress to dementia — points to consequences that extend beyond one family. Anne Byers explicitly challenged the sport's institutions when she said, "The NHL can do better to protect its players’ safety," and added, "Athletes deserve to know what head injuries can do so they can make informed decisions about their bodies and work in an environment that supports their health first."
For researchers, teammates and fans the question now is what the growing stack of posthumous diagnoses will change. Byers’ case enters a body of evidence already noted by researchers at Boston University and advocacy organizations; the family and doctors released the findings to push that evidence into public view and to press for awareness of the risks associated with repeated head trauma.
Anne Byers’ decision to make the diagnosis public ensures Lyndon Byers’ name will be part of that debate. "He was so fun and vibrant but towards the end it got to the point where didn’t want to socialize or even leave the house," she said, and then promised to carry the work forward: "I will do whatever I can to make sure nobody else has to watch their loved one deteriorate like that." That vow is now the clearest next step: the family intends to use the result to push for greater attention to player safety and informed choices about head injuries.
