Carlisle was fined $35,000 for kicking the ball with 9:34 to go in the fourth quarter of the Mavericks' 95-86 loss Wednesday to Oklahoma City.
He said he aimed at a game official but the ball instead went into the stands and hit a young boy. Carlisle later apologized to the boy, who was uninjured.
Carlisle was ejected from the game for his actions.
Mavericks owner Mark Cuban was fined $75,000 for his comments about the officiating in the game.
