He has a medical exemption to return to the PGA Tour whenever he feels he's ready. But Lyle said Friday he won't be rushing back to the U.S. until he knows he's physically capable.
"I don't want to waste the medical starts that I have," he said.
Otherwise, he was enthused about his return.
"I've done it; I've come here and achieved the biggest goal I've set myself for the week and that was to play four rounds of golf," Lyle said. "I couldn't be happier than what I am."
Scott said he and the other Australian golfers were all hoping Lyle would make it to the weekend.
"It's phenomenal. He's a beauty," Scott said. "I'm so happy for him. To see him finish 1-over, it's great. We love having him back."
