Newton dropped to the floor as he left the pitch for treatment, and the league wants assurances that concussion protocols were followed correctly.
Two weeks after the National Football League had revised its concussion protocol, it was apparently broken on the big stage.
According to the revised rule, a player is required to go to the locker room for evaluation if he is found to demonstrate "gross or sustained vertical instability (e.g., stumbling or falling to the ground when trying to stand)".
Dimitrov to face Kyrgios in Brisbane semis
Dimitrov was the first to come to his aid, leaping the net and sprinting over to help his opponent up and guide him to his chair. Kyle Edmund survives two three-set epic matches in order to reach the quarterfinals action at the 2018 Brisbane International .
Newton took a shot to the head from Saints defensive tackle David Onyemata midway through the fourth quarter. He was replaced the next play, but as he made his way off the sideline he stubbled and needed help to get back up off the field. Medical personnel looked at him as a he took a seat, and Newton missed one play as Derek Anderson relieved him.
Both Newton and head coach Ron Rivera indicated after the game that he was poked in the eye and wasn't dealing with symptoms of a head injury.
"We did everything the right way", Hurney said (per the Charlotte Observer). The league and players' union conducted probes a year ago after Newton took a hard hit to the head late in the season opener at Denver but did not come out of the game.
