Williams had X-rays, which were negative, but the Jazz said he wouldn't return to the game.
Williams pulled up for a 3-pointer midway through the period. He made contact with Chicago guard Derrick Rose when elevating for the shot and fell to the floor. Rose was called for a foul on the play.
Williams was carried off the court by two teammates as he grimaced in pain. He then left the floor for the locker room in a wheelchair.
