Russell Westbrook, whose knee injury kept him out of most of last year's NBA playoffs as well as numerous games this season, had to be helped off the court tonight in Toronto after suffering what the Thunder are calling a knee sprain.

On the play, Kyle Lowry accidentally crashes into Westbrook's knee, causing it to flex in an especially painful-looking manner. Westbrook is coming off a DNP in order to rest the knee, which has been operated on twice this season already.

That's pretty much all anybody knows at this point, and we'll try to provide updates as any more information becomes available.
