Miami Dolphins quarterback Tua Tagovailoa has been placed in concussion protocol for the second time this season.
Dolphins head coach Mike McDaniel said Monday that Tagovailoa suffered a concussion sometime during the team's loss against the Green Bay Packers on Christmas Day, despite playing the full game.
"As far as the game was concerned, no one recognized anything with regard to any sort of hit," he said. "I can't really tell you exactly what it was."
