Forward Harrison Barnes sustained a sprained left ankle in the third quarter of the Warriors vs. Suns game Friday night in Phoenix.
He will not return, the Warriors announced.
Barnes was injured when he leaped to defend a shot by Suns forward Markieff Morris, only to have his left foot land atop the left foot of Morris with 9:03 left in the third quarter.
Barnes was assisted into the locker room, at which time the injury was diagnosed. He had seven points and seven rebounds at the time of his exit, in 21 minutes played.
