The meeting, which included NBA president of league and basketball operations Joel Litvin, executive vice president of basketball operations Stu Jackson and director of officials Ronnie Nunn, plus Crawford and his attorney, ended without a resolution.
Crawford declined comment, according to the Philadelphia Daily News. The league refused comment as well, according to the newspaper.
Crawford was supsended on April 17 and didn't work the NBA playoffs. In the April 15 game, he ejected Duncan, saying at the time that Duncan "was complaining the whole game."
Duncan said after the game: "He looked at me and said 'Do you want to fight? Do you want to fight? If he wants to fight, we can fight. I don't have any problem with him, but we can do it if he wants to. I have no reason why in the middle of a game he would yell at me 'Do you want to fight?' "
In May, the head of the NBA players association said the players would welcome Crawford back.
