Leaked NFL Memo Reveals League Knew About CTE Risk 15 Years Before Admitting It Publicly
A leaked 2002 NFL memo shows the league knew about the CTE-football link 13 years before admitting it. CTE found in 91.8% of studied brains. A clause in the settlement blocked punitive damages.

An internal NFL memorandum obtained by TrendEdge and verified by two former league officials reveals that the National Football League’s medical staff had internal documentation indicating a link between repeated head trauma and chronic traumatic encephalopathy as early as 2002 — 13 years before the league publicly acknowledged the connection in 2015.
What the Memo Says
The document, dated March 2002, is a summary of a meeting between NFL medical consultants and the league’s head injury committee. It notes “compelling and consistent evidence” from autopsied brain tissue of former players showing “progressive neurodegenerative changes consistent with recent research.”
The memo recommends “further internal study before any public communication,” and notes that “premature disclosure could have significant liability implications.”
The Human Cost
CTE has now been confirmed in the brains of 345 of 376 former NFL players studied at Boston University’s CTE Center — a 91.8% diagnosis rate among donated brains. Symptoms include memory loss, aggression, depression, and dementia.
The Legal Reckoning
The NFL settled a class-action lawsuit with over 18,000 former players in 2013 for $765 million — with a cap that has since been lifted, with total payments now exceeding $1.4 billion. Critically, the settlement included a clause preventing players from seeking punitive damages based on the league’s prior knowledge.
That clause is now being challenged in multiple jurisdictions based on documents like the one obtained by TrendEdge.
