Report: Former NFL QB Earl Morrall had Stage 4 CTE /

Former NFL quarterback Earl Morrall was found to have Stage 4 CTE (chronic traumatic encephalopathy), when he died in April 2014 at age 79, his family toldThe New York Times.

CTE, which is measured on a scale from one to four, has been linked with repeated head trauma, such as the blows delivered in football. The disease can cause memory loss and depression, among other symptoms. Boston University has now found CTE in 90 of the 94 former NFL players it has studied, seven of which were quarterbacks.

When Morrall died in 2014, his family said it was due to complications from Parkinson’s disease.
