Johanna Konta's maiden French Open semi-final has been pushed back to Friday after rain washed out Wednesday's play in Paris.
The British number one, 28, was set to meet Czech teenager Marketa Vondrousova in the last four on Thursday.
But downpours on Wednesday meant the remaining women's singles quarter-finals could not be played.
They will take place on Thursday instead, with both semi-finals now on Friday.
Konta, seeded 26th, is bidding to become the first British woman to reach the French Open final since Sue Barker in 1976.
Romania's defending champion Simona Halep was due to play American teenager Amanda Anisimova in their quarter-final on Wednesday, while Australian eighth seed Ashleigh Barty was scheduled to meet American 14th seed Madison Keys.
