The Dolphins need to be held accountable for Tua Tagovailoa's injuries. 3:44

Tua Tagovailoa remained in the concussion protocol after he hit his head against the turf.

The Dolphins coach said that Tagovailoa had a head ache. The team was waiting for the results from theMRI, which was done out of "extra precautionary" on top of the other scans taken the night before.

He didn't have a timetable on when Tagovailoa might be back.

"I'm not even thinking about when he's going to play or how long he's going to be with us," he said. It's all about Tua.

Tagovailoa was sacked by a defensive tackle. He was thrown to the ground on the play. Tagovailoa's fingers were frozen in front of his face while he was on the ground.

He was taken off the field on a stretcher after he remained down for more than seven minutes. He was taken to a hospital.

The Dolphins said he was conscious and moving around in his body. He returned to Miami with the team.

Tagovailoa was talking to his teammates on the plane. He spoke to him about the game.

He was a normal Tua.

Two weeks after throwing a career-high six touchdown passes in Week 2 against Baltimore, Tua Tagovailoa is out with an injury.

The former Alabama quarterback has had an up and down career in the league.

Following a college career that included a national championship, the Dolphins drafted Tagovailoa in the first round.

When that didn't happen as quickly as Miami thought it would, there were questions about whether to stick with the young quarterback or go somewhere else.

Tagovailoa seemed to be answering those questions through the first three weeks of the season, efficiently utilizing the weapons that Miami surrounded him with during the off-season.

Tagovailoa is second in the league in passing yards with 1,035 and he has thrown 10 touchdown with three picks.

As Alabama's starting quarterback, Tagovailoa had a hip injury that required surgery.

Tagovailoa appeared to hit his head on the turf after being hit by Milano in the first half. He was evaluated for a concussion after he stumbled when he got up. He returned to the game at the start of the third quarter, despite questions about why he was allowed to return to the game at all.

He said that Tagovailoa did not have a head injury.

My job is to make sure the players are happy. I think that's very serious. Nobody in the building strays from that.

There was no medical indication that there was anything pertaining to the head. I would not have been able to live with myself if I had put someone out there.

It was difficult to see Tagovailoa leave the game.

The Ravens lost to the Dolphins in the second week of the season.

I couldn't believe what I saw yesterday. I was shocked by what I saw last Sunday. Harbaugh said it was amazing to see. I have been a coach for 40 years and have never seen anything like it before. I was not sure what I was seeing.

Sometimes you have to say no to players when they want to play. No has to be the solution.

Hurts was a college teammate of his.

Hurts said it's a scary moment for anyone to be that way.
