Curry played 30 of the first 33 game action minutes and finished with 37 points in 42 minutes in the 104-91 victory over the Cleveland Cavaliers. Golden State leads the best-of-seven series 3-2.
After his postgame news conference, the league MVP appeared to be in discomfort as his father, Dell Curry, and Warriors security guard Ralph Walker ushered him to the locker room. Once there, Curry received drinking fluids to relieve the dehydration.
Curry was watching SportsCenter highlights of the game while receiving treatment, according to the team.
Curry will be on the team's flight to Cleveland at 1 p.m. ET and should be "fine" going forward, the team said. He is expected to play in Game 6 of the NBA Finals on Tuesday, when the Warriors have a chance to win their first title in 40 years.
