The NBA is close to approving a second bubble in Chicago for the eight teams that were not invited to play in Orlando.

Teams will have mini-training camps and games against other teams with a target date of September.

Several teams had been pushing for the concept over the past few weeks. 

Seven of the eight non-playoff teams participated in a call Thursday with league officials, with the New York Knicks as the lone team without a representative on the call.

The play would be similar to a summer league format.

"How they frame it is almost irrelevant to us," one general manager told ESPN. "It's more a chance to get our young guys out there working with some game simulation."
