PHOENIX — Warriors forward Omri Casspi has officially been ruled out of Monday night's game against San Antonio with a sprained right ankle. After draining a seven-foot hook shot early in the second quarter of Friday night's loss to Sacramento, Casspi came down awkwardly, rolling his right ankle. He was tended to by a team trainer before leaving the floor on his own power, ending his night with six points in six minutes. An MRI later confirmed that Casspi, who didn't join the team for its current road trip, had sprained his right ankle. Though Golden State isn't ready to put a timetable on Casspi's return, Yahoo Sports reported Saturday that he would miss roughly a week.
