The NBA fined Golden State Warriors forward Draymond Green $50,000 on Wednesday for questioning the integrity of game officials during Game 3 of the Western Conference semifinals.

Specifically, the league said in a statement that Green made “an inappropriate comment that questions the integrity of game officials.” Green made a comment directed at the officials referring to the 5.5-point spread of the game, ESPN reported.

Green fouled out of the game midway through the fourth quarter in a 102-97 loss to the Minnesota Timberwolves on Saturday.

Green finished with two points on 1-of-4 shooting in the game. He’s averaging 10.8 points, 5.3 rebounds and 4.3 assists in the four games so far.

Minnesota leads 3-1 in the best-of-seven series with Game 5 on Wednesday night in Minneapolis.
