Late Cowboys Star Marshawn Kneeland Had Stage 1 CTE When He Died By Suicide

Former Dallas Cowboys player Marshawn Kneeland had stage 1 chronic traumatic encephalopathy (CTE) when he died by suicide in 2025, according to a brain analysis. CTE, a progressive brain disease often linked to repeated head trauma, raises serious questions about the long-term effects of football on players' mental health. This discovery underscores the need for better understanding and prevention of CTE in sports, especially given the increasing evidence linking the disease to suicide. It's a sobering reminder of the hidden toll that head injuries in contact sports may take on athletes' lives.
