Adam Silver said the NBA remains committed to resuming the season but that there is still no timetable for when or even a deadline for canceling.

Silver spoke with reporters on Friday following the NBA's board of governors meeting.

"Based on the reports that we got from varied outside officials, current public health officials ... we are not in a position to make any decisions," Silver said. "And it's unclear when we will be."

Silver said the NBA is watching to see whether the number of new infections decreases, and is monitoring the availability of testing on a large scale and the path toward a potential vaccine and antiviral drugs. The NBA also is paying close attention to what the Centers for Disease Control and Prevention is directing on a federal level and what the various state rules are.

"There is a lot of data that all has to be melded together to help make these decisions," Silver said. "That is part of the uncertainty. We are not even at the point where we can say if only A, B and C were met, then there is a clear path.

"I think there is still too much uncertainty at this point to say precisely how we move forward. I'll add that the underlying principle remains the health and well-being of NBA players and everyone involved. We begin with that as paramount."
