NFL’s concussion protocol modified after Tagovailoa review

MIAMI GARDENS, Fla. (AP) — The NFL and NFL Players Association have agreed to make changes to the league’s concussion protocol following a joint investigation into the procedures after Miami Dolphins quarterback Tua Tagovailoa suffered what was described as a back injury against the Buffalo Bills last month. The league and players’ union said in a joint statement Saturday that the Dolphins followed the league’s protocol after the injury, but 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.
