Lydia Ko will be unable to defend her Saudi Ladies International title on the greens in Jeddah next week, being forced to withdraw from the event due to Covid-19.
Ko returned a positive test for the virus, which will keep her out of the $1million tournament.
It will halt what has been a strong start to the season for the 24-year-old. A 23rd-place finish at HSBC Women's Championship earlier this month was the lowest she had finished in three tournaments so far this year.
Ko started the season off with two tournaments in Florida – earning a top-10 finish at the Diamond Resorts Tournament of Champions in Orlando, before winning the Gainbridge LPGA title in Boca Raton.
It was her 17th LPGA title, and had commentators hailing the return of the real Lydia Ko as she prevailed in a battle with close friend Danielle Kang, with the win earning her another point towards Hall of Fame membership.
