The new coach of the Vancouver Canucks John Tortorella has asked his players to steer clear of social media websites from now on.
Tortorella was named just the 17th coach in Canucks history in June of this year having previously been with the New York Rangers and the Tampa Bay Lightning.
He has now attempted to stamp his authority by discouraging his new players from using Twitter and the like.
Although not banning it completely, Tortorella has said that any information leaked from the locker room on to Twitter will lead to punishment.
Several players including Roberto Luongo, David Booth and Alex Burrows are currently on Twitter and Tortorella has told them to be careful in future.
Tortorella, who ironically has his own Twitter account, says the social media site means "nothing but trouble," insisting anything said in the locker room must "stay in the room."
A look of the coach's own Twitter account shows that it is primarily used for fundraising purposes rather than leaking confidential information.
