Jason Day collapsed while walking the ninth hole at Chambers Bay and was attended to by medical personnel for what was reported to be dizziness.
Day, playing his final hole of the day during the second round of the U.S. Open, was able to stand after he was on the ground for a few minutes and finished the hole with a bogey 4.
"I turned around and he was laying down there,” said Jordan Spieth, who played the first two rounds with Day. "I just wanted to turn the cameras away and make sure he got the right treatment ... He didn't say much (in the scorer's tent), he just signed the card. Justin (Rose) and I were both telling him to get some rest and get some water."
This comes just weeks after Day withdrew from the AT&T Byron Nelson. During his press conference this week, Day was asked about that WD and medical tests that followed.
"I feel good," he said. "I had three sleep studies done. I had a lot of blood tests done. I had an MRI on my head and my back—my head and my neck. And everything came back negative. So I have no idea what that was, other than I just may have been exhausted.”
Greg Norman, part of the Fox sports team broadcasting the U.S. Open, spoke with Day and said he hopes to continue the tournament.
UPDATE No. 1: Jason Day's agent, Bud Martin, released a statement following Day's round.
"Jason is being treated on site at Chambers Bay, after feeling dizzy near the end of his round. We will provide more information later today after getting through the medical evaluation process. Jason wants to express his appreciation for all the good wishes from so many fans and friends.”
UPDATE No. 2: Day's agent once again.
“Jason was diagnosed to have suffered from Benign Positional Vertigo. He was treated locally by Dr. Robert Stoecker and Dr. Charles Souliere and is resting comfortably. His condition is being monitored closely and he is hopeful he will be able to compete this weekend in the final rounds of the U.S. Open. He wants to thank all who treated him at the Franciscan Medical Group and thank all of the fans and friends who have reached out to he and his family.”
