Gregg Popovich sent his best players home, deciding they reached the end of the road before the trip was over.
For that, and for keeping it a secret, the San Antonio Spurs were fined $250,000 by the NBA on Friday.
Commissioner David Stern said the Spurs "did a disservice to the league and our fans" when they didn't bring Tim Duncan, Tony Parker, Manu Ginobili or Danny Green to Miami for the final game of the six-game trip.
"The result here is dictated by the totality of the facts in this case," Stern said in a statement. "The Spurs decided to make four of their top players unavailable for an early-season game that was the team's only regular-season visit to Miami. The team also did this without informing the Heat, the media, or the league office in a timely way. Under these circumstances, I have concluded that the Spurs did a disservice to the league and our fans."
Teams are required to report as soon as they know a player will not travel because of injury.
The league's statement said the Spurs were in violation of league policy reviewed with the board of governors in April 2010 against resting players in a manner "contrary to the best interests of the NBA."
The Spurs didn't comment on the penalty.
The issue of resting healthy players has been debated before, though usually at the end of the season, not a month into it. And the Spurs have been right at the center of it, Popovich using the rest strategy for an aging team that could use more time off than the NBA schedule often allows.
They even made a joke out of it last season, the box score listing "OLD" next to the 36-year-old Duncan's name as the reason he didn't play.
