The NBA has already postponed two games this week — one game in Dallas on Monday night between the Mavericks and New Orleans Pelicans, and another in Chicago on Tuesday between the Bulls and Celtics.
The Mavericks had four players test positive for coronavirus, according to multiple reports.

On Monday, the NBA and its players’ union met to discuss modifying some of the league’s health and safety protocols.
