When the Warriors take the floor for the first game at Chase Center on Saturday night, Kevon Looney will not be in uniform. The center won't play against the Los Angeles Lakers because of a hamstring strain, coach Steve Kerr told reporters Thursday after practice. Looney -- who spent a good portion of the offseason rehabbing the costal cartilage fracture he sustained during the NBA Finals against the Toronto Raptors -- tweaked his hamstring during practice Wednesday.
