The collision occurred on Highway 24 in Oakland, California, around 9am, the California Highway Patrol reported.
The CHP said Curry's car was hit when a car spun out and hit it. Then, the black Porsche was rear-ended by a second car.
The CHP said the rainy weather likely contributed to the crash. Curry, 30, has been sidelined since suffering a groin injury on November 8 in a game against Milwaukee.
He has missed seven games, and the team has not set a date for his return. ESPN reported he will miss Friday night's game against Portland and will not play on Saturday against Sacramento.

His father, former NBA player Dell Curry, told KTVU in the Bay Area after the collision that his son was not injured.
"He's OK. We just want his groin injury to heal," the elder Curry said.
Golden State have posted a 2-5 record while he's been out with the injury. The Warriors return to action on Friday night for a clash with the Portland Trail Blazers.
