Your life is worth more than $10 billion, 'cause you can't replace your life. You have only one life."While Omalu feels the NFL shouldn't have allowed Tagovailoa to step back onto the field, he did say that it ultimately falls on the quarterback, who decided to re-enter the game."The duty falls on the players. The NFL did not point a gun on his head and say, 'You must go back to play.' He could have said no."TMZ@TMZFamed neuropathologist Bennet Omalu tells TMZ Sports Tua Tagovailoa put his life at risk by returning to the Bills game after hitting his head Sunday. tmz.com/2022/09/27/ben…233Famed neuropathologist Bennet Omalu tells TMZ Sports Tua Tagovailoa put his life at risk by returning to the Bills game after hitting his head Sunday. tmz.com/2022/09/27/ben…While video footage shows a dazed Tagovailoa trying to get up from his feet but stumbling a few times, the quarterback denied it was due to a head injury or concussion.
