Dallas Mavericks superstar Luka Doncic is out for a key game in the Western Conference playoff race, sitting the second night of a back-to-back Friday because of right knee soreness. Doncic will miss the second meeting with Golden State in four days as the MVP candidate and league scoring leader tries to guide the Mavs into a guaranteed playoff spot in the top six in the West. The quick rematch with the Warriors comes a night after Dallas' 109-95 victory over Atlanta.
