Dr. Bennet Omalu, the renowned neuropathologist whose discovery of chronic traumatic encephalopathy (CTE) in football players inspired the movie "Concussion," is willing to "bet my medical license" that O.J. Simpson may be suffering from the disease.
"O.J. Simpson is more likely than not to suffer from CTE," Dr. Omalu told ABC News earlier this week. "... I would bet my medical license on it."
CTE is believed to be caused by repeated blows to the head. It has been found mostly in athletes who play contact sports, such as football. Multiple NFL players -- including Frank Gifford and Junior Seau -- have been diagnosed with CTE after their deaths.
