Tua back at practice, rookie Thompson to start Week 6 for Dolphins

Miami Dolphins quarterback Tua Tagovailoa will return to the field and throw Wednesday as part of his progression through concussion protocol, head coach Mike McDaniel announced, according to ESPN's Marcel Louis-Jacques.

McDaniel added that Tagovailoa won't play Sunday against the Minnesota Vikings.

Miami plans to start Skylar Thompson at quarterback in Week 6, McDaniel said, according to Louis-Jacques. Thompson, a seventh-round rookie, completed 57.5% of his passes for 166 yards and no touchdowns against one interception in the team's Week 5 loss to the New York Jets after entering the game to replace an injured Teddy Bridgewater.

Bridgewater started in Week 5 but left the game after just one play to be evaluated for a concussion. He passed testing but still landed in concussion protocol after a spotter saw the quarterback stumble.

McDaniel said if Bridgewater clears concussion protocol before the Vikings game, he'll serve as Thompson's backup, according to USA Today's Safid Deen.

The Dolphins don't have another quarterback on the active roster but they signed Reid Sinnett to the practice squad last week.

Tagovailoa suffered a concussion in Week 4 against the Cincinnati Bengals. He was stretchered off after his head appeared to hit the field on a sack. The incident came days after he exited Miami's Week 3 contest versus the Buffalo Bills looking disoriented following a hit late in the second quarter. The 24-year-old cleared concussion protocol at halftime and returned to that game.

The NFL and players' association modified the concussion protocol following a joint investigation into the league's procedures after Tagovailoa's incident against the Bills.
