US Open champion Emma Raducanu has withdrawn from the upcoming Kremlin Cup in Moscow.
No official reason has been given for pulling out of next week's event.
Raducanu is still scheduled to play in Romania and Austria before the end of the season.
The world number 22, who was ranked 150 at the start of September's US Open which she went on to sensational win as a qualifier, said she was not "putting any pressure" on herself after her early exit at Indian Wells.
"In my mind I'm so inexperienced that I'm just taking it all in," she said.
