Major League Baseball, the National Basketball Association, Major League Soccer and the National Hockey League issued a joint statement on Monday stating that locker room access will be temporarily restricted to players and essential staff.
The measures are being taken to help try to control the spread of the novel coronavirus.
"After consultation with infectious disease and public health experts and given the issues associated with close contact in pre- and post-game settings, all team locker rooms and clubhouses will be open only to players and essential employees of teams and team facilities until further notice," the statement said.
While the ban keeps media members out of the clubhouse, the statement also says that access will be maintained "in designated locations outside of the locker room and clubhouse setting."
The changes for all leagues will be effective beginning Tuesday with scheduled games and practices. There are, however, no plans to ban fans from games or postpone any action.
The statement concludes by saying the leagues will keep their eye on the situation and take the steps necessary for "a safe and welcoming environment."
