Dolphins will add quarterback after Tua Tagovailoa sustains 3rd ...

The Miami Dolphins will bring in another quarterback while starter Tua Tagovailoa deals with his latest concussion, head coach Mike McDaniel said Friday.

For now, Skylar Thompson will be considered the starter while Tagovailoa is sidelined. Tagovailoa left Thursday night's 31-10 loss to Buffalo in the third quarter with the third known concussion of his NFL career, all of them coming in the last 24 months.

"The team and the organization are very confident in Skylar," McDaniel said.

McDaniel said the team has not made any decision about whether to place Tagovailoa on injured reserve. Tagovailoa was expected at the team facility on Friday to start the process of being evaluated in earnest.

"We just have to operate in the unknown and be prepared for every situation," McDaniel said, noting the only opinions that will matter to the team will be the ones from Tagovailoa and the medical staff.

McDaniel added he doesn't see Tagovailoa playing in Miami's next game at Seattle on Sept. 22.

"I have no idea and I'm not going to all of a sudden start making decisions that I don't even see myself involved in the most important parts of," McDaniel added. "All I'm telling Tua is everyone is counting on you to be a dad and be a dad this weekend. And then we'll move from there. There won't be any talk about where we're going in that regard … none of that will happen without doctors' expertise and the actual player."

Tagovailoa was hurt Thursday after running into Bills defensive back Damar Hamlin and hitting the back of his head against the turf on a fourth-down keeper with about 4:30 left in the third quarter.

He went straight ahead into Hamlin and did not slide, leading with his right shoulder instead.

Tagovailoa remained down for about two minutes before getting to his feet and walking to the sideline. He made his way to the tunnel not long afterward, looking into the stands before smiling and departing toward the locker room.

Tagovailoa appeared to be making a fist with his right hand as he lay on the ground. It was movement consistent with something that is referred to as the "fencing response," which can be common after a traumatic brain injury.

The Dolphins needed almost no time before announcing it was a concussion. The team said he had two during the 2022 season, and Tagovailoa was diagnosed with another concussion when he was a college player at Alabama.

McDaniel said Tagovailoa would get "proper procedural evaluation" and "appropriate care" on Friday.

"The furthest thing from my mind is, 'What is the timeline?' We just need to evaluate and just worry about my teammate, like the rest of the guys are," McDaniel said. "We'll get more information [Friday] and take it day by day from here."

Some players saw Tagovailoa in the locker room after the game and said they were encouraged. Tagovailoa spoke with some players and then went home after the game, McDaniel said.

"I have a lot of love for Tua, built a great relationship with him," said quarterback Skylar Thompson, who replaced Tagovailoa after the injury. "You care about the person more than the player and everybody in the organization would say the same thing. Just really praying for Tua and hopefully everything will come out all right."

Tagovailoa was 17 for 25 passing for 145 yards, with one touchdown and three interceptions — one of which was returned for a Buffalo score — when he got hurt. Thompson completed eight of 14 passes for 80 yards.

Thompson said he feels "fully equipped" to run the Dolphins' offence.

"What's going to lie ahead, who knows, but man, I'm confident, though," Thompson said after Thursday's game. "I feel like I'm ready for whatever's to come. I'm going to prepare and work hard and do everything I can to lead this team and do my job."

Tagovailoa signed a four-year, $212 million US extension before this season — a deal that makes him one of the highest-paid players in the NFL — and was the NFL's leading passer in Week 1 this season. Tagovailoa left with the Dolphins trailing 31-10, and that was the final score.

"If you know Tua outside of football, you can't help but feel for him," Bills quarterback Josh Allen said on Amazon following the game. "He's a great football player but he's an even greater human being. He's one of the best humans on the planet. I've got a lot of love for him and I'm just praying for him and his family, hoping everything's OK. But it's tough, man. This game of football that we play, it's got its highs and it's got its lows — and this is one of the lows."

Tagovailoa's college years and first three NFL seasons were marred by injury, though he positioned himself for a big pay bump with an injury-free and productive 2023 as he led the Dolphins into the playoffs. He threw for 29 touchdowns and a league-best 4,624 yards last year.
