Draymond Green sprained his ankle in the 4th quarter of the Golden State Warriors' 118-112 loss to the Houston Rockets.
Green, who did not return to the game, will be re-evaluated on Sunday.
Steve Kerr added that he didn't think the injury was serious.
"I talked to Draymond briefly and he said he thought he sprained the same one early in the game. A little tweak. We'll see. I don't think it's a really serious injury, but we'll have an update [Sunday] I guess," said Kerr.
