Jason Day’s frustrating golf season continues, the Queenslander withdrawing during the third round of the World Golf Championship’s Bridgestone Invitational due to vertigo, likely a direct result of his treatment for other ailments.

But while he has been put to rest on doctors orders he should still be able to take his place at the PGA Championship, the last major of the year, next week at Valhalla in Louisville, Kentucky.

Day had completed just two holes on Saturday at Firestone Country Club before pulling the plug and a specialist in Akron later diagnosed he had an episode of benign paroxysmal positional vertigo or BPPV.

The 26-year-old went through a procedure to alleviate the issue and has been told to rest for the next 24 to 48 hours to allow his equilibrium to return.

While there are several causes of vertigo, the specialist believed the problem was Day’s recent need of cortisone for his thumb injury and anti-inflammatory drugs for persistent throat issues.

Day has had a season punctured by injury and illness since breaking through to win the WGC Match Play Championship in February.

A left thumb and wrist problem has hampered the Australian consistently, cutting down his practice time and forcing withdrawals from a handful of tournaments.

He was trialling a new grip this week in Akron to lessen the pain associated with the injury but was six over par for the tournament when he walked off.

Day has also dealt with multiple bouts of strep throat and tonsillitis and took medication for the illness after the second round, then felt dizzy overnight.
