Jaylen Brown was hit with a fine after making what the NBA called an "inappropriate gesture."

The Boston Celtics star motioned his thumb across his throat shortly after a dunk on Wednesday.

Brown threw down a two-handed dunk against the Detroit Pistons on Isaiah Stewart, and then made the gesture in Stewart's direction.

Brown told the media after the 130-120 victory over the Pistons that he expected to hear from the NBA for his actions.

Well, he has been hit with a $25,000 fine.

It's only the second fine in the NBA this season for an "obscene gesture," according to Spotrac.  Anthony Edwards was fined $35,000 for giving the middle finger.

NBA RETURNING TO CHINA AFTER FRICTION BETWEEN LEAGUE, COUNTRY: REPORT

Players were hit with fines last year due to gestures, perhaps most notably Rudy Gobert, when he seemed to indicate that referees had money on a game. That cost him $100,000.

Brown had 28 points with nine assists, and Kristaps Porzingis added 26 points and nine rebounds to lead the Celtics to their ninth victory in 10 games.

The Celtics held a double-digit lead until the fourth quarter, when Detroit hit four straight three-pointers to come within eight points, 109-101, and force Boston coach Joe Mazzulla to put Brown back in.
