MIAMI — When Gregg Popovich gives his best players a night off to rest, it’s not uncommon for the San Antonio Spurs coach to get letters from upset fans.

This time, he’s going to hear from an upset commissioner — even after nearly knocking off the Miami Heat.

The Heat rallied to beat the Spurs 105-100 on Thursday night — digging deep despite San Antonio’s decision to have four top players resting at home in a move that bothered NBA Commissioner David Stern.

The Spurs played without Tim Duncan, Tony Parker, Manu Ginobili and Danny Green, all sent back to San Antonio.

Stern called the decision “unacceptable,” apologizing to fans.
