The sides reached a tentative agreement early Saturday to end the 149-day lockout and hope to begin the delayed season with a marquee tripleheader Dec. 25. Most of a season that seemed in jeopardy of being lost entirely will be salvaged if both sides approve the handshake deal.

Barring a change in scheduling, the 2011-12 season will open with the Boston Celtics at New York Knicks, followed by Miami at Dallas in an NBA finals rematch before MVP Derrick Rose and Chicago visiting Kobe Bryant and the Lakers.

Neither side provided many specifics about the deal, and there are still legal hurdles that must be cleared before gymnasiums are open again.

“We thought it was in both of our interest to try to reach a resolution and save the game,” union executive director Billy Hunter said.

After a secret meeting earlier this week that got the broken process back on track, the sides met for more than 15 hours Friday, working to save the season. Stern said the agreement was “subject to a variety of approvals and very complex machinations, but we’re optimistic that will all come to pass and that the NBA season will begin Dec. 25.”

The league plans a 66-game season and aims to open training camps Dec. 9, with free agency opening at the same time. Stern has said it would take about 30 days from an agreement to playing the first game.

“All I feel right now is `finally,”’ Miami Heat star Dwyane Wade told The Associated Press.

Just 12 days after talks broke down and Stern declared the NBA could be headed to a “nuclear winter,” he sat next to Hunter to announce the 10-year deal, with either side able to opt out after the sixth year.

“For myself, it’s great to be a part of this particular moment in terms of giving our fans what they wanted and wanted to see,” said Derek Fisher, the president of the players’ association.
