Golden State Warriors forward Draymond Green was fined US$50,000 by the NBA on Wednesday for making an inappropriate comment questioning the integrity of game officials, the league announced.

Green's comments were made during Golden State's 102-97 home loss to the Minnesota Timberwolves in game three of their Western Conference semi-final series last Saturday.

No details were given for the exact comment Green made to incur the fine.

The Timberwolves own a 3-1 lead in the best-of-seven series entering game five on Wednesday at Minneapolis. (AFP)
