SEATTLE -- Washington has lost running back Deontae Cooper to yet another torn anterior cruciate ligament, the third time he has had the injury since becoming a member of the Huskies.

Washington coach Steve Sarkisian announced the injury to Cooper's right knee Wednesday night, saying it occurred during a non-contact drill in practice. Sarkisian was "saddened and dismayed" by the news of yet another knee injury for the promising prospect.

Cooper missed his first two seasons at Washington after twice tearing the ACL in his left knee. Cooper was expected to be slowly worked back into the mix at running back with the Huskies looking to replace Chris Polk. Cooper has yet to play a game in college because of his knee injuries.
