Although the MRI revealed no new structural damage, Green is doubtful to play in Friday night's game against the New Orleans Pelicans, the team said.
Toward the end of the third quarter, Green was fouled during a running jumper and landed awkwardly. He immediately began hobbling and rubbing his left knee.
Moments later the quarter buzzer sounded, and Green retreated to the locker room, where he was diagnosed with a left knee strain. He did not return to the game.
"I'll be good. I'm fine," Green told ESPN after the game, as he walked gingerly out of the locker room.
He finished with 9 points, 11 rebounds and 13 assists in 28 minutes.
New Orleans is the first stop on a three-game road trip for Golden State. The Warriors said Green is traveling with the team on the road trip.
