Miami Dolphins quarterback Tua Tagovailoa will return to team practice on Wednesday and could be cleared from concussion protocol ahead of Sunday's matchup against the Minnesota Vikings.

Tagovailoa suffered a concussion during a defeat to the Cincinnati Bengals last month and was taken by ambulance to hospital, subsequently missing the Dolphins' loss to the New York Jets.

While highly unlikely to take to the field in Week 6 against the Vikings, NFL Network's Tom Pelissero and Ian Rapoport state sources say he has made 'great strides' and is heading in the 'right direction' for a return to the field.

Tagovailoa has consulted with four independent specialists since the injury and increased his rehab work to include cardio and strength training over the weekend, while Wednesday will involve throwing the ball as part of "non-contact sports-specific activity".

The Dolphins quarterback situation is up in the air ahead of Sunday, with backup QB Terry Bridgewater also in concussion protocol and coach Mike McDaniel telling reporters on Monday there was no specific timeframe for the return of either player.

Rookie seventh-round pick Skylar Thompson took to the field in place of Bridgewater against the Jets, where he threw for 166 yards and one interception, finishing with a pass completion percentage of 57.6 per cent.

The Dolphins are on a two-game losing streak, sitting 3-2 after beginning the 2022 season with three successive wins.
