His campaign to publicize the plight of former football players who died from cumulative knocks to the Thead put the league on the defensive. The NFL fought back, trying to discredit Omalu and downplay the brain disease he discovered, CTE, or chronic traumatic encephalopathy. His story was told in the 2015 film Concussion, where he was played by Will Smith. In 2002, Omalu was working as a forensic pathologist in the county coroner’s office in Pittsburgh, Pa., when he did an autopsy of all-star pro football player “Iron Mike” Webster. Omalu determined that Webster’s brain had been injured by the cumulative effect of numerous subconcussive head injuries he suffered over his 17 seasons in the NFL. From 2004 through 2008, Omalu did autopsies of NFL play- Bennet Omalu, MD ers, wrestlers, and military veterans including, but not limited to, Terry Long, Justin Strzelczyk, Andre Waters, Chris Benoit and Tom McHale, and determined CTE to be an underlying cause or contribu- tory factor to the death of these athletes and military veterans. Today, Omalu is the chief medical examiner for ’s San Joaquin County as well as a clinical professor of pathology and laboratory medicine at University of California, Davis. He explained details of CTE — and discussed his views on allowing children to play football.
