The NFL Players Association has fired off a blunt warning to its members after a sobering new study on brain disease.
Research published Tuesday in the British Medical Journal found that nearly a quarter of football players who died between 2016 and 2021 had chronic traumatic encephalopathy (CTE). The study, which examined brains donated for research, revealed that 315 of 338 players (93%) whose brains were studied from 2008 to 2021 were diagnosed with the degenerative condition, which can only be confirmed after death.
In a memo obtained by Pro Football Talk, the NFLPA told players that the findings are "a sobering reminder that football carries serious risks that can have lasting consequences for players and their families." The union emphasized that protecting player health is a core priority.
"We understand that studies like this can create concern for you and your loved ones," the memo continued. "At the same time, they should not diminish hope." The union pointed out that many symptoms linked to CTE—such as memory issues, mood swings, depression, anxiety, sleep problems, and cognitive struggles—could also stem from other treatable conditions. "That is why a thorough medical evaluation is so important," the memo stressed.
The NFLPA also highlighted that one of the study's lead researchers, Dr. Daniel Daneshvar, noted that many CTE-related symptoms are "treatable with the right care." The union said it has made "major investments in brain health research" to support players.
The memo frames the study as a "call to action across the entire football ecosystem," urging everyone from the league to teams to share responsibility in advancing research, improving access to care, and developing better treatments. "While we have learned a great deal over the past two decades, there is more work to do," it read.
Players are being told to pay close attention to their cognitive and neurological health and to seek evaluation if they have concerns. "Early intervention matters. Resources are available today that can help," the memo concluded.
The study's release comes as the NFL continues to grapple with the long-term health impacts of the game. The league has faced scrutiny over its handling of head injuries, and this new data could intensify that debate. The NFLPA's proactive communication signals a heightened sense of urgency.
For fans, the news is a stark reminder of the risks players take every Sunday. It also underscores the importance of ongoing research and support for retired athletes. Meanwhile, the NFLPA's message is clear: knowledge is power, and players must be proactive about their health.
