Washington announced the results of an MRI on Jarreau's injured knee on Wednesday morning.
Jarreau was injured when he went down awkwardly on a breakaway with 18:25 left in the first half of the opener against Seattle on Sunday. Jarreau appeared to be clipped by Seattle's Isiah Umipig as he went up for the basket and he landed in a heap. Jarreau was on the court for several minutes before being helped to the locker room.
Jarreau was expected to be a starter for the Huskies. He had 17 points and nine rebounds in the Huskies' exhibition win over Central Washington.
