The NBA and the NBA Players Association have agreed to a labor contract that still needs to be ratified by both sides, the league and the union said late on Friday.

Details of the agreement will be made available once the term sheet is finalized, the sides said.

The age limit to enter the NBA will remain at 19 years old, which means most players coming out of high school will have to wait at least one year before entering the league, the source said

The deal includes the addition of an in-season tournament, the removal of marijuana as a banned substance, and a second luxury tax tier, a source with knowledge of the negotiations told Reuters, confirming an earlier report by the New York Times.
