NFLPA agrees to concussion protocol changes, urges NFL to do the same 6:03 PM ET ESPN The NFL Players Association has agreed to changes to the concussion protocol and is urging the NFL to do the same before Sunday's games kick off. The announcement comes in the wake of a review over how Miami Dolphins quarterback Tua Tagovailoa 's concussion evaluation was handled in Week 3. "Our union has agreed to change the concussion protocols to protect players from returning to play in the case of any similar incident to what we saw on September 25," the NFLPA Board and Executive Committee said in a statement Friday. "We would like these changes to go into effect before this weekend's games to immediately protect the players and hope the NFL accepts the changes before then as well."

He was immediately taken to the locker room with a head injury, the team announced at the time. He passed the locker room evaluation, however, and returned to finish the game after halftime with both Tagovailoa and the Dolphins clarifying that his stumble was caused by a back injury he suffered earlier in the game. Four days later, Tagovailoa was taken to a local hospital after his head hit the turf late in a Week 4 game against the Cincinnati Bengals . He was diagnosed with a concussion and is ruled out for Sunday's game against the Minnesota Vikings . The NFLPA initiated its right to request a review of the NFL's concussion protocol following Tagovailoa's quick return to the game and terminated the unaffiliated neurotrauma consultant who initially evaluated the quarterback during the Bills game. The NFL and NFLPA have both said they are committed to altering the concussion protocol based on what both parties learned during the review. ESPN's Marcel Louis-Jacques contributed to this report.
