The Golden State Warriors are getting their first significant test of the season.

One day after 10-time All-NBA star Stephen Curry was forced to leave Sunday night’s loss against the Clippers with a foot injury, an MRI confirmed he has a left peroneal strain, the team said Monday in a statement. The Warriors added there was no structural damage, and Curry would be reevaluated Friday.

Though no more details were provided, the foot injury can take up to several weeks to heal, depending on severity, perthe Cleveland Clinic.

The injury took place with 7:55 left to play in the game and happened when Curry was trying to set a screen. He appeared to step awkwardly and tweak his left foot, immediately limping off the court. Curry, who has a history of sprained ankles, was immediately helped into the locker room and did not return.

Golden State lost the game 112-104 and Curry recorded 18 points on 6-for-11 shooting, six assists and four rebounds before his removal.

“He’s doing OK,” Kerr said Sunday after the game. “I think he used the word ‘mild’ or ‘moderate.’ He has obviously sprained that ankle many times before, so he doesn’t think it’s too bad, but, obviously, it’s a concern.”

Curry had actually first tweaked the ankle late in the third quarter, which prompted his removal from the game. After he and the Golden State training staff treated the ankle, using resistance bands to stretch the foot, Curry eventually returned to the game just before suffering the final tweak.

Curry, 36, is averaging 18.3 points, 6.7 assists and 5.3 rebounds per game. The Warriors (2-1) return to the court Tuesday night when they host the New Orleans Pelicans.
