WASHINGTON — The NHL is revamping its concussion monitoring system for the upcoming season.

Deputy Commissioner Bill Daly says the league will have four concussion spotters watching all games from a centralized location in either Toronto or New York, as well as spotters at each game to check for visible symptoms. Those spotters will have the authority to have players removed from games.

Previously, there had been team-affiliated concussion spotters in each arena and they could recommend but not require players be removed from a game.

Daly says the new concussion policy goes into effect for the eight-team World Cup of Hockey, which begins Saturday in Toronto, and that the NHL will release more details closer to the start of the regular season.
