The Concussion Legacy Foundation released a study Wednesday that revealed former college football players from over 100 programs had chronic traumatic encephalopathy (CTE).
In total, 138 former football players out of 152 studied at the VA-BU-CLF Brain Bank, or 91 percent, were diagnosed with the degenerative brain disease.
As Kevin McGuire of College Football Talk noted: "How far back the study goes is not clear, but it does include at least one player from the 1969 Texas Longhorns, Greg Ploetz. The former defensive tackle died of dementia in May 2015, and it is believed he suffered from long-term effects of playing football while at Texas.
