"The results of the joint review determined that the protocol was triggered when Mr. Wilson was directed to the sideline for an evaluation after the referee, Walt Anderson, concluded that a medical examination was warranted," the joint statement read. "Nonetheless, the required evaluation was not conducted and Mr. Wilson was permitted to return to the game without an evaluation. Once it is determined that a medical examination is warranted, a player may only be cleared to return by the medical staff; Mr. Wilson's return to the field without a sideline concussion evaluation was therefore in violation of the Concussion Protocol. Subsequently the team medical staff did examine the player and clear him per the protocol."
