Dolphins quarterback Tua Tagovailoa will officially start this week's Thursday Night Football game against the Bengals.

Tagovailoa will match up with fellow 2020 NFL draft class Joe Burrow in Cincinnati. The Dolphins have a plan in place in case Tagovailoa cannot finish the game.

They activated starting quarterback Skylar Thompson, who will act as the third string behind Teddy Bridgewater.

Rookie 7th-round QB Skylar Thompson is active for tonight's game, so Teddy Bridgewater has some insurance if something comes up with Tua.

The Miami star was questionable Wednesday as he continued to recover from a back injury suffered Sunday against the Bills.

Tagovailoa was hit by Bills linebacker Matt Milan late in the second quarter and was seen stumbling after the game. He left the game and cleared the concussion protocol,

After the game, the quarterback was dealing with the concussion protocol and told reporters his "back was locked" after the hit, which caused him to stumble.

The NFLPA is reportedly investigating the Dolphins' handling of Tagovailoa's concussion protocol, according to NFL Network's Tom Pelissero.
