Irv Cross, former NFL defensive back-turned-legendary CBS sports broadcaster, has been diagnosed with stage 4 chronic traumatic encephalopathy, Boston University researchers announced Tuesday.
Cross died on Feb. 28, 2021, and had been previously been diagnosed with mild cognitive dementia dating back to ’18. Stage 4 of CTE is the most advanced stage and can only be diagnosed in a postmortem examination.
The two-time Pro Bowler sustained multiple blows to the head during his NFL career. When Cross was still alive, he experienced changes in his mood swings, depression, memory loss, maintaining balance as well as being in denial about the disease.
