Buddy Hield has just been fined $25,000 by the NBA ... and it's all 'cause he flipped off someone during the Pacers vs. Hornets game on Monday night.
League Exec Joe Dumars announced the punishment for the Indiana star on Wednesday afternoon ... after he was spotted shootin' the bird not once, but twice while on his team's bench.
The incident occurred with 11:30 left in the second quarter of the game ... as Hield was sitting next to Tyrese Haliburton.
Cameras showed Buddy appeared to be locked in on something .
