The Machine is down for repairs after absorbing an elbow to the grill. From the Lakers’ website: “Lakers guard Sasha Vujacic suffered a concussion after being inadvertently struck in the face, just below the left eye, by an errant elbow from Lamar Odom in Thursday’s practice. Vujacic will be monitored closely and re-evaluated on Friday, but for now is considered out indefinitely from basketball activity.”
