Former NFL cornerback Irv Cross, who went on to become the first Black network sports show anchor, was posthumously diagnosed with Stage 4 CTE after nearly a decade of playing in the league, the Boston University CTE Center announced Tuesday. 

The two-time Pro Bowler was drafted by the Philadelphia Eagles in 1961 and played there until he was traded to the Los Angeles Rams in 1966. He returned to Philadelphia, in 1969, where he retired. He then went on to have a successful career in broadcasting, most notably with CBS.

In 2021, at the age of 81, Cross died. Just a few years earlier, he had been diagnosed with mild cognitive dementia.

"Mr. Cross was diagnosed during life with mild cognitive impairment and was found at autopsy to have stage 4 chronic traumatic encephalopathy (CTE), which is the most severe type of the disease," BC CTE Center director and neurologist Dr. Ann McKee said in a statement Tuesday.

"Through his brain donation, Mr. Cross’ legacy will be able to help increase our understanding of CTE in living contact sport athletes and others who have experienced repetitive head trauma." 

Cross was one of 345 former players diagnosed with CTE through Boston University’s research center and one of 376 studied.
