Former Alabama quarterback Tua Tagovailoa concerned many when he returned to the contest against the Buffalo Bills on Sunday after slamming his head into the turf.

Well-known neuropathologist Bennet Omalu had some thoughts on the situation, telling TMZ Sports that he thought Tagovailoa put his life at risk with his actions. Omalu is under the impression that Tagovailoa never should have come back into the game after he was initially out of it.

“Your life should be worth more to you than any amount of money,” Omalu, who discovered CTE, said. “Your life is worth more than $10 billion, ’cause you can’t replace your life. You have only one life.”

Tagovailoa has insisted he does not have a head injury, saying rather that he hurt his back.

“I got up, and that’s kind of why I stumbled,” he said in there postgame press conference. “My back kind of locked up on me. But for the most part, I’m good. Passed whatever concussion protocol they had.”

Regardless, the quarterback’s apparent state when he came back into the game is one that just didn’t look right and raised plenty of safety-related questions in an instance where he looked like he shouldn’t have been headed anywhere but the sideline.

Tagovailoa and the Dolphins are set to take on the Cincinnati Bengals on the road Thursday at 7:15 p.m. CT.
