Golf took a back seat as Australian golfer Jason Day collapsed on the final hole of his second round of the US Open.
Walking down the steep 9th hole, Day wobbled and fell to the ground and did not rise for several minutes.
While receiving medical treatment, the Queenslander complained of eyesight problems and a repeat attack of vertigo that forced him out of last month’s Byron Nelson Classic in Texas.
After more than five minutes, Day gingerly stood up and was helped down the steep fairway desperate to complete his round.
He buckled again before entering the bunker to play his second shot, going down on his knee and taking another swig of water from caddie and mentor Col Swatton.
Bravely, Day finished the hole, making bogey and signing for an even-par 70 to remain two under and well in contention.
But golf will be the furthest thing from the 27-year-old’s family and friends who rushed to his side as soon as possible.
Day left the green via a golf cart to the scorer’s hut and completed the formalities before being taken from Chambers Bay in a van via his nearby motorhome for further treatment.
Playing partner Jordan Spieth said the incident had been frightening.
“I turned around and he was laying down. All I heard was (he suffered) dizziness,” Spieth said.
“I’m not really sure what happened – we just wanted to keep the cameras away and let him get better.
“He could barely walk to finish the hole … he was pretty brave.
“(In the scorer’s hut) … he was fine, he didn’t say much just signed the card.
“Justin (Rose) and I just told him to get some rest and water.
“I was happy (Jason and) I could … finish up, but first and foremost it’s good that he’s healthy.
“Let’s hope he’s OK.”
Spieth said he didn’t notice any precursors and that the incident had come “out of nowhere”.
Greg Norman, Day’s former Presidents Cup captain, rushed down from his Fox Sports commentary role to check on his fellow Queenslander’s health.
“His head was down, his eyes were going back and forth and he said I have vertigo,” Norman told Fox Sports.
“He said, `I’ll be OK’.
“Col Swatton said it was exactly what had happened at Firestone (in Ohio) last year and he had to withdraw.
“He’s a tough kid. It’s a little confusing for him because he doesn’t know what the issues are.
“He knows there’s something there … let’s just hope he gets better very quickly.”
Day said before the tournament that he’d had a battery of tests after his recent scare in Texas and that all had come back negative and that he was “fit and ready to go”.
“I’ve struggled a little bit with energy sort of stuff and it all started in New Orleans (at the PGA Tour’s Zurich Classic), and I was feeling a little shaky on the golf course, losing energy and strength,” he told Golf Australia on Sunday.
“But I had blood tests and an MRI scan on my head and my neck and had three sleep studies just to rule out what was going on.
“All the blood tests came back negative, the MRI was negative, so there’s nothing wrong with me – other than doing stupid stuff on the golf course occasionally,” he joked.
“We are just waiting for the third sleep study to come back, but I feel good – best I’ve felt in a while.”
Day’s wife Ellie is expecting their second child in November.
