Already down three All-Stars, the Warriors lost their fourth midway through the first half on Monday night.
With just over nine minutes remaining in the second quarter against the Spurs, Draymond Green took a knee from a driving Danny Green.
Draymond was in immediate pain and left the court for the locker room.
Just before the end of the first half, NBC Sports Bay Area's Kerith Burke reported that Green was ruled out for the rest of the game with a "midsection issue."
Early in the second half, the Warriors diagnosed that Green suffered a pelvic contusion and that x-rays were negative.
The Warriors are currently playing without Stephen Curry, Klay Thompson and Kevin Durant. All three are dealing with injuries that will keep them out several games.
