An investigation by the NFL and NFLPA determined that Dolphins quarterback Tua Tagovailoa did not show concussion symptoms during last Sunday's game.

Tagovailoa was able to finish the Christmas Day game against the Packers. On Monday, he was placed in concussion protocol after reporting symptoms to the team. Dolphins head coach Mike McDaniel later confirmed that the quarterback was in the protocol for the second time this season.

The league and players association's joint review concluded that there were no violations of the concussion protocol during the game.
