Less than a month away from the restart of the 2019-20 NBA season, a number of players and staff have tested positive for the coronavirus. Commissioner Adam Silver is aware of this and expressed much concern that a positive test while in the Orlando campus might cause the bubble to pop.

Silver spoke with Fortune Brainstorm Health in an online interview and shared the possible situations that might arise in the NBA Orlando bubble location.

“We won't be surprised when they first come down to Orlando if we have some additional players test positive,” the NBA Commissioner said, as transcribed by ESPN. “What would be most concerning is once players enter this campus and then go through our quarantine period, then if they were to test positive or if we were to have any positive tests, we would know we would have an issue.”

“… We would know that there's in essence a hole in our bubble or that our quarantine or our campus is not working in some way,” Silver added later. “So that would be very concerning.”

The rise in cases among players and staff have raised concerns whether or not the NBA season will be canceled outright. Silver emphasized that the season won't be shut down due to one positive coronavirus test. However, if it spreads, then this might finally end the 2019-20 campaign for good.

Nevertheless, Adam Silver is optimistic that the league and its health partners can contain the virus.

“I think we do have the ability to trace, of course to try to understand where that positive case came from,” Silver said of any positive cases inside the Walt Disney World campus. “We can actually analyze the virus itself and try to track whether there is more than one case, if it's in essence the same virus and same genetic variation of the virus that is passed from one player to another or two people have gotten it on the campus independently. So those are all things that we are looking at.”

From the looks of it, the NBA is fully prepared for what's coming and what might happen.
