Jason Day was walking toward the ninth green -- his last hole of the day -- at Chambers Bay on Day 2 of the U.S. Open when the Aussie suddenly fell while walking toward the putting surface.
Day remained on the ground for almost 10 minutes while medical staff made their way to where he fell, as Day remained in place. It initially seemed that Day had perhaps injured his ankle walking on the hillside. Several spectators and a few caddies have injured themselves trying to walk on this slick, dry fescue surfaces. However, it appears Day actually simply fell over walking to the green.
The Aussie did get up and finish the round, making a bogey to card an even-par 70. Day signed his scorecard, then was transported away from the course for further evaluation.

“Jason is being treated on site at Chambers Bay, after feeling dizzy near the end of his round," said Day's agent, Bud Martin, in a statement. "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.”
Day has been battling vertigo-like symptoms for some four years, according to what Day's wife, Ellie, told Golf Channel. It's affected his game to the point that he withdrew from the AT&T Byron Nelson in May after experiencing that dizziness on the course. He also pulled out of last year's WGC-Bridgestone Invitational for the same reason.
Earlier in the week, Day spoke about trying to figure out the cause of the dizziness. As of Monday, Day was still unclear on the reasons why, saying he had taken part in a few personal sleep studies to hopefully understand what might be creating the dizziness.
