Miami Dolphins quarterback Tua Tagovailoa after suffering a second hit to the head in as many games last week.
The NFL and the players’ union say they anticipate imminent changes to the sport’s concussion protocol after a pair of incidents involving violent hits to the head of Miami Dolphins quarterback Tua Tagovailoa reinvigorated concerns about head injuries in the game and how they are handled.
The NFL Players Association has also dismissed an independent doctor who was involved in evaluating Tagovailoa after he hit his head against the ground last Sunday and then allowed him to return to the field, according to a person familiar with the matter. The doctor’s identity is not known.
