Late Cowboys player Marshawn Kneeland diagnosed with CTE
Late Cowboys player Marshawn Kneeland diagnosed with CTE

Former Cowboys defensive end Marshawn Kneeland was posthumously diagnosed with Stage 1 chronic traumatic encephalopathy (CTE). … Kneeland died by suicide in November 2025 at the age of 24. … Boston University's CTE Center made the diagnosis after Kneeland's family donated his brain for research. There are four stages of CTE, with Stage 4 showing the most damage.
Kneeland's family, including his girlfriend, Catalina Mancera, put out a statement Tuesday. … "While this diagnosis does not change the tragedy of his passing, it provides important context about some of the struggles he may have been facing," the statement read. "We share this information to help people understand what NFL and other high contact sport athletes might be struggling with. Raising awareness is important to us. We continue to remember Marshawn with compassion for the person he was, rather than defining him by the final moments of his life. One Love."
The BU CTE Center made a point of saying that suicide is "complex and multifactorial" and "a post-mortem CTE diagnosis should not be considered the cause of a suicide."
According to records obtained by ESPN, there had been concerns about Kneeland's mental health as far back as 2020 when he was at Western Michigan. In one incident, he was required to turn in his firearm to police until he was cleared by a counselor. … In another, a friend called authorities with concern over Kneeland's well-being. He was found on railroad tracks, saying he hoped a train would run him over. He was hospitalized.
