Former New York Giants safety Tyler Sash was found to have an extraordinarily high level of CTE when he died in September at the age of 27, The New York Times reported Tuesday.
Sash died from an accidental overdose of painkillers, and his family donated his brain to be studied for chronic traumatic encephalopathy. The Times reports that "representatives from Boston University and the Concussion Legacy Foundation notified the Sash family that CTE had been diagnosed in Tyler's brain and that the disease, which can only be confirmed only posthumously, had advanced to a stage rarely seen in someone his age.
