The NBA commissioner David Stern has set a deadline of 11 o'clock this morning for the world's top basketballers to accept his latest offer, or get a worse deal on the table.
But the players union say they won't be backing down in the dispute.
The league has offered a 50-50 split of basketball-related income and the commissioner has said the offer will switch to 53-47 in favour of the owners, unless an agreement is reached to end the lockout.
The league has cancelled all games up until the end of November, and there are fears that Christmas games could come under threat if a deal isn't reached in the near future.
