Jordan publicly lambasted officials after the Cleveland Cavaliers beat the Wizards, 97-96, in Game Three of their Eastern Conference quarterfinal series on April 28.
The Washington Post reported Wednesday the fine was assessed the day after the game, but was never confirmed until Tuesday by NBA spokesman Tim Frank.
"The NBA does not always announce fines," Frank told the newspaper. "Jordan is one of several individuals who have been hit with fines for criticizing referees during this year's playoffs."
"I'm not going to get fined for saying what's obvious," Jordan told the newspaper on April 29 before the fine was levied. "Everybody sees it (but) the truth is the truth."
Neither Jordan nor the team has commented on or verified the fine.
Cleveland beat Washington in six games to advance to the Eastern Conference semifinals, where the Cavs lost to Detroit in seven games.
