Former two-time NBA MVP and Golden State Warriors point guard Stephen Curry has been fined $US50,000 ($A64,000) by the league for throwing his mouthpiece in the direction of a referee during Saturday's game against the Memphis Grizzlies, the NBA announced Monday afternoon.

Curry threw his mouthpiece in the direction of a referee in response to a no-call on drive with 43.6 seconds remaining in an eventual 111-101 loss for the Warriors.

Curry and teammate Kevin Durant were both ejected from the game after arguing with officials about the incident. Durant was not fined.

Golden State forward Andrew Iguodala was also fined $US15,000 by the NBA for verbally abusing an official during the incident.

It is the second instance Curry has been fined by the NBA for throwing his mouthpiece.

He was fined $US25,000 for throwing his mouthpiece into the crowd and hitting a fan in Game 6 of the 2016 NBA Finals.

Curry is averaging 29.0 points, 5.0 assists and 4.7 rebounds this season.
