NBA vice president Stu Jackson announced the fine on Friday.
Paul missed a shot late in regulation Wednesday night that gave New Jersey a chance to force overtime, then turned the ball over with 19 seconds left and the Hornets trailing by two. His attempt at a buzzer-beating 3-pointer bounced out and New Orleans lost 103-101.
The four-time All-Star guard finished 4 for 15 from the field and turned the ball over seven times in the game. He said afterward that he felt "like this was my loss."
