Nobody did anything wrong.

That’s the bottom line following a review of the manner in which the NFL concussion protocol was applied to Miami Dolphins quarterback Tua Tagovailoa last week.

The NFL and NFL Players Association on Saturday issued a joint statement following a review of the situation in which Tagovailoa apparently suffered a concussion during the Dolphins game versus the Green Bay Packers. In that episode no symptoms were obvious during the game, he was not examined for a concussion, and not placed in the protocol.

Tagovailoa was placed in the protocol on Monday when the Dolphins noticed possible symptoms. And the league announced a review of the entire process soon afterward.
