With Trevor Ariza trying to get to the rim, Curry came over the top in an attempt to deny his shot, but fell over the back of Ariza and landed heavily.
He appeared to fall hard on his shoulder, and lay motionless for a while before eventually walking to the locker room.
A stretcher was brought out, but the MVP was able to walk off the court by himself.
In the middle of the third quarter, doctors cleared Curry to return after he passed the league's concussion protocol.
