The Chicago ‘bubble’ will not likely be mandatory for the eight NBA teams, per Chris Fedor of Cleveland.com.

The league is planning to create a second ‘bubble’ in Chicago, which will include the eight teams that will not play in Orlando.

“I’m told the second bubble idea still needs to be approved by the players association. There are details to be worked out. The early word, according to sources, is it wouldn’t be mandatory,” Fedor tweeted.
