The NBA is confident they can secure the bubble from positive COVID-19 cases, but Adam Silver said on Tuesday that any significant number of positive tests inside the protected campus could result in a second shut down of the season.

"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 if 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."

"Certainly if we had any sort of significant spread within our campus, we would be shut down again."
