NFL concussion: rule changes needed for Sunday's games says players' union

The players association wants the league to make rule changes about concussions.

Tua Tagovailoa suffered a head injury against the Buffalo Bills and was allowed to play on.

He left the field with a concussion four days later.

Changes are needed, but not when they will be made.

The Green Bay Packers are playing the New York Giants.

"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 25 September," the league's players' union said.

We want these changes to go into effect before this weekend's games to make sure the players are protected, and we hope the league accepts the change before then.

Changes to the joint NFL-NFLPA protocols are necessary to further enhance player safety according to the league.

The leadership of the Unaffiliated Neurotrauma Consultants and Independent Certified Athletic Trainers who serve as spotters have already been spoken to.

Dolphins coach Mike McDaniel said that Tagovailoa won't play against the New York Jets on Sunday and is seeing several outside specialists to find out what's going on.
