Sonics guard Luke Ridnour broke his nose in the preseason opener and will have to wear a mask for at least the next month.

Ridnour caught an elbow from Sacramento's Ron Artest midway through the first quarter Tuesday night. Ridnour was examined in Sacramento, but underwent additional tests Wednesday in Seattle. A CT scan revealed a non-displaced fracture of the nasal bone.

Ridnour was being fitted for a mask that he will have to wear for at least the next month, and the team said he would be a game-time decision for Friday's preseason game at Cleveland.
