The NBA has canceled the remainder of its preseason games on Tuesday after failing to come to a labor agreement, and if there is no deal reached by Monday the first two weeks of the regular season will be canceled, according to ESPN.

The players and the owners met for four hours on Tuesday, but came no closer to moving away from the impasse in negotiations. This is in spite of a discussion of a 50-50 split of the income between the two sides.

“We were not able to make the progress that we hoped we could make and we were not able to continue the negotiations,” said NBA commissioner David Stern.

No further meetings are scheduled. The players have been locked out since July 1, and have in the months that have followed the lockout seen few signs of progress of getting a deal done. Which is why there is a real possibility of regular season games being missed.

“By Monday, we will have no choice but to cancel the first two weeks of the season,” Stern said.
