Golden State center Andris Biedrins sprained his right ankle in the team's loss to Phoenix on Friday night.

Biedrins grimaced in pain at the end of the third quarter as he lay on the ground with his ankle held in the air.

"I thought we had a chance to win," Warriors coach Don Nelson said of the 115-105 loss. "But when Goose went down, it really made it difficult for us."

X-rays on Biedrins' ankle came back negative, and he will be re-evaluated on Saturday to determine the severity of the sprain.
