Green picked up two technical fouls, which is an automatic ejection.
The first came a minute and a half into the second quarter when he argued with official Tre Maddox that a foul he was charged with was a clean strip. The second occurred when he challenged Deyonta Davis at the rim and was whistled for the foul; right after the play, Green was seen raising his right hand in disdain in the direction of referee Nick Buchert, and the official quickly tossed him.
Green walked off the court without further issues. He refused to comment after the game, saying, "Nah, I'm going to save my money."
"I don't know what (Green) said," Warriors coach Steve Kerr said. "It didn't look like it warranted an ejection, but I was a hundred feet away, so it's hard for me to really tell you what happened. But it seemed like a quick trigger."
These were Green's ninth and 10th technical fouls of the season and his second ejection.
Rookie Jordan Bell started in place of Green in the second half and finished with 11 points. Golden State is off until Wednesday, when it visits Dallas.
