The NBA has considered a number of possible alternatives in light of the compounding COVID-19 virus, including pushing its season back, according to The Athletic's Sam Amick.
The league has reportedly been asking teams to give their arena schedules through the end of July, indicating that they are exploring the possibility of postponing play for at least a month. Typically, the NBA postseason ends in early June.
On Wednesday, the Wizards and Kings announced that they will play games as scheduled—with fans in attendance—but that is subject to change. The Warriors announced that they will play all home games in front of an empty Chase Center for the foreseeable future after San Francisco officials banned public gatherings of more than 1,000 people.
