The Warriors were trailing the Memphis Grizzlies by eight with under a minute to go when Curry drove to the basket and missed a layup. Curry thought he was fouled on the play, took his mouthpiece out and immediately threw it in the direction of the referee.
Curry was immediately ejected.
Durant was also ejected for arguing the call.
Shortly afterwards, as both players were walking to the locker room, Durant could be seen trash-talking with Grizzlies fans and showing them his ring finger, presumably to indicate that he has a championship ring and the Grizzlies do not.
After the game, Curry took responsibility for throwing the mouthpiece but denied that he was throwing it at the referee intentionally.
After the game, Warriors coach Steve Kerr joked about the incident, saying Curry should be suspended for "maybe ten games" for endangering the fans.
