Hockey’s top disciplinarian says the NHL will look at fighting as part of a larger review of head injuries in the game. In an interview with CBC’s Peter Mansbridge, former player Brendan Shanahan said no decisions have been made “but there’s no way we would ever deny that it’s not something we’re looking at closely.” Despite the double negative, it appears clear that Shanahan is serious about cracking down on blows to the head and other dangerous hits. Under his guidance, the NHL has already handed down seven suspensions for dangerous play this preseason.
