BOSTON (AP) Phoenix Suns forward Amare Stoudemire had to be helped off the court after spraining his left ankle in the second quarter of Friday night's game against the Boston Celtics.

Stoudemire went to the floor after landing on Paul Pierce's foot under the Suns' basket.

Last season's rookie of the year is averaging 15.6 points and 9.1 rebounds. He had five points and six rebounds before the injury.
