Curry, the Warriors' second-leading scorer, was hurt in the second quarter of Wednesday's 111-94 loss to the San Antonio Spurs. The second-year guard was dribbling behind the 3-point line when he hunched over, called a timeout and fell to the ground in pain. He was helped off the court by teammates and did not return.
Curry later underwent X-rays which were negative.
"He's going to be out for a little bit," Golden State coach Keith Smart said. "We're re-evaluating him day by day to see how the ankle is responding to the rest and treatment."
Curry sprained the same ankle in three straight games earlier this season. The injury eventually forced him to miss two games, though the ankle didn't appear to be giving Curry much problem lately until he rolled it against the Spurs.
"You've got to be a little bit concerned because now he's rolling it without stepping on someone," Smart said. "It's fatiguing out a little bit. It's kind of shutting down."
Curry didn't seem too concerned and hopes the additional rest will help speed his recovery. Following Friday's game against the Heat, the Warriors play back-to-backs at Utah on Monday and against Minnesota on Tuesday.
"My body heals pretty fast," Curry said. "I've just got to make sure the strength is back, and that's the thing that you can't really measure. I can do all of the tests that I want to, but there's no telling if it will feel the same after three games in four days."
