According to ESPN.com, the NHL has enacted a social media policy that will prohibit most posts by players, coaches, trainers and management on game days.

Beginning at 11 a.m. on the day of a game, and ending after post-game media obligations, the aforementioned NHL employees won’t be allowed to post on social media websites. Nor can they use another person to post messages to their social media accounts.

Several Ducks players have popular Twitter accounts: Bobby Ryan, Matt Beleskey, George Parros, Cam Fowler, Andrew Gordon, Kyle Palmieri, Peter Holland and Emerson Etem.

The NHL is relatively late in restricting social media use by its personnel. Two years ago, the NFL instituted a policy similar in scope — blacking out social media statements less than 90 minutes before kickoff up until post-game media obligations commence. The NBA’s initial policy, also enacted in 2009, was almost identical.

Enacted in May, Major League Baseball’s policy (which you can download here) seems more focused on restricting the content of social media dispatches, rather than their time of day.

Incidentally, Parros endorsed a social-media-use restriction on his own earlier today.
