Curry was hurt in the fourth quarter of Golden State's 98-87 win over Utah Monday, scoring 22 points before leaving with the injury.
He came out after tangling with 6-foot-9, 240-pound Marvin Williams of the Jazz, who landed on Curry's head as they both fell to the floor.
He left the court with a towel wrapped around his head.
The Warriors said Tuesday Curry's only symptom was a mild headache that later dissipated.
He leads the team in assists with 8.7 per game and is second in scoring with 19.9 points per game.
