UPDATE:
The NBA has fined the Spurs for sitting out its players versus the Heat in last night's contest. Here is the official statement.
NEW YORK, Nov. 30, 2012 — The NBA announced today that the San Antonio Spurs organization has been fined $250,000 for its decision to send four players home prior to the Spurs' Nov. 29 game in Miami. The Spurs' actions were in violation of a league policy, reviewed with the NBA Board of Governors in April 2010, against resting players in a manner contrary to the best interests of the NBA.
However, according to the video below which was posted by ESPN yesterday, it's being reported by ESPN's Marc Stein that no punishment will be given to the Spurs. Granted anything can change considering no official statement from the league has been handed out. Should anything change, we will update this post accordingly.

If this is true, this comes as a big blow to Stern's already damaged credibility. It's a huge embarrassment to the league for him to come out and announce an announcement in a hot headed moment and promising to do something out of his realm of authority. Stern is stepping down on February 1, 2014 as commissioner and giving the reigns to deputy commissioner Adam Silver.
