The National Football League said it will modify its concussion protocol to enhance player safety after an investigation of the injury to a Miami Dolphins quarterback. 

The move comes after Tua Tagovailoa displayed signs of apparent brain trauma when he was slammed head first into the turf during a Sept. 29 game in Cincinnati. The injury, the second sustained by Tagovailoa in less than a week, had ignited a flurry of criticism against the league’s concussion protocol.
