Stephen Curry hit the floor hard going up for a block defending Trevor Ariza.

Curry tumbled over Ariza and appeared to land on his shoulder and then his head banged hard against the floor.

Curry was face down on the floor for several minutes, but he was able to walk off the court and into the locker room on his own power.

The Golden State Warriors said Curry suffered a head contusion, but no injury to the shoulder. 

Curry passed the concussion protocol and returned to the game in the third quarter.

Bob Myers insisted to Ethan Sherwood Strauss that Curry didn't suffer a concussion.

"If he did, he wouldn't have played. That's pretty hard line," said Myers.

"It's all minor stuff compared to how it looked," said Curry.
