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.

With center Willie Cauley-Stein sidelined for training camp because of a left foot strain, it appears Omari Spellman will start on Saturday.

Golden State acquired the big man from Atlanta in mid-July in the trade that sent Damian Jones to the Atlanta Hawks.

Spellman appeared in 46 games as a rookie last season, averaging 5.9 points and 4.2 rebounds while making 34.4 percent of his 3-point attempts.

Additionally, second-round pick Alen Smailagic is undergoing an MRI on Thursday afternoon after rolling his ankle during Wednesday's practice.
