The National Basketball Players Association's executive committee has voted to set aside a portion of this past season's salary shortfall while a plan to fund health costs for retired players is studied.

Union leaders agreed that they liked the concept of funding retired players' medical costs, but no vote was taken on whether to go forward with the plan.

Since the players' negotiated salaries for the 2014-15 season came in below their 50-51 percent negotiated guarantee, the union will receive the entire escrow fund of approximately $200 million plus the amount of the shortfall -- estimated to be $57 million, according to a league source.
