While sources denied rumors that David Stern's retirement is not imminent, he hinted at it during comments he made on Thursday.

"I would say it's fair to say this is my last (labor agreement)," said Stern. "This is a 10-year deal, with a re-opener at six," he said, explaining that either side can opt out after six seasons. "I'm not planning to be here certainly for the 10 and probably not the six."

Asked later if he had already decided when he would retire, Stern said "no." Asked if he would simply retire whenever he felt like it, he said "yes."
