Tua Tagovailoa has entered the NFL's concussion protocol in the wake of the Miami Dolphins' loss to the Green Bay Packers on Sunday.

Mike McDaniel said Tagovailoa displayed and admitted to having concussion symptoms when he spoke with team doctors Monday and was immediately placed into the protocol.

It marks the second time this season Tagovailoa has been placed into the protocol.

Tagovailoa previously entered the concussion protocol after the Dolphins' game against the Cincinnati Bengals in Week 4 and was hospitalized briefly then after his head hit the turf.

He went on to miss the team's next two games and returned in Week 7.
