Dante Exum appeared to suffer a dislocated shoulder during Friday's preseason game.
Exum collided with TJ Warren on a drive to the basket and crashed to the floor.
Exum was undergoing an MRI on Friday night to determine the extent of the injury, and Utah coach Quin Snyder didn’t sound optimistic.
“I don’t want to speculate,” Snyder said. “But if you saw the shoulder, it didn’t look good.”
