England's number one female golfer Charley Hull has revealed she has tested positive for coronavirus and will miss the ANA Inspiration.
The second women's major of the year begins at Mission Hills Country Club, California, on Thursday.
Hull, 24, said she is now self-isolating and working with the LPGA Tour on contact tracing.
"I didn't feel great yesterday (Monday) but I put it down to jet lag, the heat and my asthma playing up," she said.
"I now realise I have some mild symptoms which feel similar to having a cold.
"I am very disappointed to have to withdraw from what is one of my favourite events of the year.
