Basketball fans in Memphis went streaming for the exits in droves during the third quarter during a game between the Grizzlies and the Los Angeles Clippers -- after signs informed fans there was an emergency -- but it was all a false alarm.
Law enforcement sources tell TMZ the drama was all over a busted water main. Someone in the stadium thought they smelled smoke and officials made the decision to evacuate the stadium.
Fans, coaches, players, TV crew, announcers -- everybody -- streamed for the exits, and the broadcast of the game dipped to black. Now, we're told local authorities have determined there is no danger and are expected to continue the game.
UPDATE: The game has resumed progress.
