Nothing will come of this.

The NFL announced that they will work with the NFLPA to gather more information on the possibility that Tom Brady suffered a concussion last season. Here is the statement from the NFL according to NESN.com.

We have reviewed all reports relating to Tom Brady from the unaffiliated neurotrauma consultants and certified athletic trainer spotters who worked at Patriots’ home and away 2016 season games as well as club injury reports that were sent to the league office,” the NFL said.

“There are no records that indicate that Mr. Brady suffered a head injury or concussion, or exhibited or complained of concussion symptoms. Today we have been in contact with the NFLPA and will work together to gather more information from the club’s medical staff and Mr. Brady. The health and safety of our players is our foremost priority and we want to ensure that all our players have and continue to receive the best care possible.”

They have to look into this, I'm not expecting any punishment, and I don't believe the Patriots trainers and coaching staff would risk putting the greatest quarterback of all time back on the field if he was suffering from concussion symptoms.
