Dolphins quarterback Tua Tagovailoa will see a neurologist this week after suffering his fourth diagnosed concussion in five years and his third while in the NFL, according to reports Sunday.

Tagovailoa is focused on getting better and gathering information and reportedly isn’t thinking about retiring.

Tagovailoa was injured on a scramble when he lowered his head and collided into Bills safety Damar Hamlin during the Dolphins’ 31-10 loss to the Bills on Thursday night.

While former players and even current Raiders coach Antonio Pierce have said Tagovailoa should retire, Dolphins coach Mike McDaniel has emphasized the importance of not offering his opinion.

“I think it would be so wrong of me to even sniff that subject and it’s more in line of actually caring about the human being, and that’s something that entirely you’re talking about his career, right?” McDaniel said. “His career is his, and that’s something that I really, really, really wish — I totally understand it and it’s not misplaced. I totally get how that’s where people want to go to.

“I just wish that people would for a second hear what I’m saying that bringing up his future is not in the best interest of him, so I’m going to plead with everybody that does genuinely care, that that should be the last thing on your mind.”
