Bennet Omalu, the neuropathologist who has been credited with finding chronic traumatic encephalopathy (CTE) in ex-football players, is once again calling on Tua Tagovailoa to step away from the game. Omalu told TMZ Sports that the Dolphins quarterback, who suffered his third known concussion on “Thursday Night Football” against the Bills this week, could become “permanently incapacitated” if he does any more damage to his brain. The doctor, who was portrayed by Will Smith in the 2015 film “Concussion” on his life and work, urged Tagovailoa to retire from the NFL for the second time in less than two years.
