Brandon Rush sustained a serious knee injury in the Warriors' game on Friday against the Grizzlies.
Rush was fouled in the air by Zach Randolph and landed awkwardly. It appeared as though Rush dislocated his left knee.
Rush will have an MRI on his injured left knee on Saturday.
Rush signed a two-year, $8 million contract in the offseason. Rush has a player option for 13-14.
