Australian golfer Jason Day is hopeful of taking to the course for the final two rounds at the U.S. Open, despite being diagnosed with vertigo.
Day, who underwent multiple tests in the lead in to the season's second major having been hampered by vertigo-like symptoms, prompted worrying scenes in Washington state on Friday after slumping to the ground with apparent dizziness prior to completing his final hole.
The 27-year-old was attended to by medics for several minutes on the ninth fairway at Chambers Bay before he later underwent tests at a nearby clinic.
"Jason was diagnosed to have suffered from benign positional vertigo," manager Bud Martin said after Day carded a second-round 70.
"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 US 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."
Friday's incident comes after Day withdrew from last month's AT&T Byron Nelson due to dizziness, having suffered from similar symptoms during the final round of the Zurich Classic of New Orleans in April.
Day also pulled out of the WGC-Bridgestone Invitational in Ohio last year because of vertigo.
Tied for ninth, Day is still the best placed Aussie, sitting two under and only three shots off the lead.
Youngster Cameron Smith is the next best placed Aussie. He's in a tie for 17th, five off the pace, while Geoff Ogilvy and Adam Scot are both one over in a tie for 21st.
Marcus Fraser is still in the hunt in a tie for 28th and two over par, with John Senden the last Aussie to make the cut. Senden is four over par, nine off the lead and tied for 44th.
