The Warriors announced that an MRI performed on Russell’s right thumb after Friday night’s loss to the Boston Celtics game confirmed the sprain.
He will not travel with the Warriors on their upcoming four-game road trip and will be re-evaluated in two weeks.
His injury is the latest setback for a Warriors team that has battled them all season. Star guard Stephen Curry broke his left hand Oct. 30 and will miss at least three months. All-Star swingman Klay Thompson continues to rehab from a torn ACL in his left knee; his return this season remains unclear. Center Kevon Looney has been out since playing 10 minutes in a season-opening loss to the LA Clippers because of a nerve condition. Jacob Evans has been out since straining his adductor Oct. 28. Damion Lee has been out since Monday because of a non-displaced fracture on his right hand. Rookie Alen Smailagic has been out all season because of a right ankle sprain.
