NEW YORK (AP) — The NBA is instituting a policy regarding Twitter and other social media sites, banning players from using them during games.

The league sent a memo to teams on Wednesday telling them that cell phones and other communication devices can’t be used from 45 minutes before game time until after players have finished their responsibilities after games. That includes halftime.

The rule applies to “coaches, players and other team basketball operations personnel.” NBA spokesman Tim Frank confirmed the memo and its contents.

The memo does not specify penalties for violation of the rule, and says teams are free to create their own policies for practices and other team events.

The NBA has more than 1.4 million followers on Twitter, and many players are active on it.
