Tom Pelissero of the NFL Network and Pro Football Talk are reporting the NFLPA has terminated the unaffiliated neurotrauma consultant involved with the Tua Concussion check last Sunday in the Dolphins-Bills game.

Per Pro Football Talk:

“Per a source with knowledge of the situation, the NFLPA has exercised its prerogative to terminate the Unaffiliated Neurotrauma Consultant involved in the decision to clear Tua to return to action.

The concussion protocol provides that players who demonstrate gross motor instability may return only if the team physician, in consultation with the UNC, determines that the instability did not have a neurological cause.

Although specific findings have not been made regarding how and why Tua returned, the union lost confidence in the UNC, given that the impairment of the player was obvious. Based on the available video, Tua should not have returned.”
