Left gear handle down. Completed remainder of the QRH checklist. Returned for an emergency overweight landing at 134000 pounds. Prior to landing; made 1 fly-by down runway 18R at 200 ft AGL for tower to visually inspect no nose gear damage and that the gear was straight. Landed runway 18R. Taxied to gate.
