During the appearance, Lawler noted that had he had his heart attack anywhere but where he was - next to a doctor during a WWE event - he'd likely have died.
Lawler also noted that he intends to return to the ring and his plan is to appear at the 10/16 Smackdown taping in Memphis. My guess is he will at least make an appearance live, but probably not announce and absolutely nothing physical.
Lawler's voice is still very, very rough from all he's been through.
