MIAMI GARDENS, Fla. — The NFL and NFL Players Association agreed to modify the league's concussion protocol following a joint investigation into the league's procedures after Miami Dolphins quarterback Tua Tagovailoa suffered an injury against the Buffalo Bills last month.
The league and players' union said in a joint statement Saturday that the outcome of the Tagovailoa case "was not what was intended when the Protocol was drafted." As a result, language addressing abnormality of balance/stability was added to the league's protocol list of symptoms that would keep a player from returning to action.
