Curry, who played through a right calf injury during a Christmas Day game against the Cleveland Cavaliers, did not practise on Tuesday because of his ailment.
He is listed as questionable for Wednesday's game against the Dallas Mavericks and Golden State are set to take on Houston Rockets on Thursday.
"There's a chance that he won't play in one or both," Walton told the San Jose Mercury News.
"That's probably going to be a game-time decision or at least determined on how he's feeling tomorrow."
After a breakout MVP campaign last season, Curry has ascended to even greater heights this time and leads the league in scoring with 30.5 points per game.
Champions Warriors (29-1) are off to the best start in NBA history but after steering clear of major injuries a season ago their health is now being tested.
Starting forward Harrison Barnes has been out for the past 13 games, shooting guard Klay Thompson missed a contest earlier this season and coach Steve Kerr (back surgeries) has yet to take the sideline.
Now Golden State's ultimate catalyst, Curry, is in question.
"He hasn't said anything except for he wants to play," Walton said.
"Even (Monday) in the game when I saw him in the game limping, and I tried to take him out, he gave the wave-off and said that it was fine."
