This is far from the first time Curry has thrown his moutpiece during a game, as he admitted to reporters.
Curry had 37 points in the contest.
In the final minute of Golden State's 111-101 loss in Memphis, things came unglued after a no-call that angered Curry enough to fling his mouthpiece.
Obviously frustrated for multiple reasons, Curry launched his mouthpiece at a referee late in the quarter on the road, and got booted from the game for his efforts. I'm not doing a great job putting together combinations, finding the right motivation to get guys going, to get some joy and some laughter in here.
Now, fans will have to wait and see if Curry will be punished, or even suspended, for launching the mouthguard at the referee, or if it'll be brushed off to the side like the last time the incident occurred.
"I didn't throw my mouthpiece at the ref".
Nonetheless, the Warriors once again did not play like champions, coach Steve Kerr said afterward. "It endangered thousands of people in the stands".
Asked to explain what happened, Durant said: "I felt Steph got fouled on that drive and I let [the referee] know about it and he threw me out". He ended up hitting the son of Cavaliers minority owner Nate Forbes with that heave.
Kevin Durant attempted to pick up the offensive slack with Curry on the bench (29 points and 13 rebounds).
The Warriors, coming off a home loss to Houston on Tuesday, had to rally from 15 down to subdue the Pelicans, getting a combined 61 points from their All-Star backcourt of Klay Thompson (33 points) and Stephen Curry (28).
