Devin Booker is officially out for rest of the season. Igor Kokoskov confirmed before Friday's final home game of the season that Booker will not play in Phoenix's final three games after rolling his left ankle in Wednesday's loss to Utah. "It's a medical reason," Kokoskov said. "The good news is the x-ray results came back negative. The timetable, unfortunately, for him to recover is not long enough to bring him back. We didn't shut him down. It's just circumstances."
