The NBA has informed teams that all games through Dec. 15 have been canceled.

The most recent collective bargaining proposal sent to the players detailed a 72-game 2011-12 NBA season that would begin on Dec. 15. The NBPA made the decision to reject that offer from the owners, and have begun to make efforts to disband their union. In doing so, they plan to try to take talks of a new collective bargaining agreement out of the negotiating room and into the courts.

Until now, NBA commissioner David Stern had only officially only canceled NBA games through Dec. 1. During an interview Stern made it clear that with the NBA players’ recent actions, the possibility of any season in 2011-12 is becoming increasingly unlikely.
