Britain's Kyle Edmund has withdrawn from the French Open with a stomach injury before his match against Nick Kyrgios.
The Englishman, 20, had been scheduled to face the Australian 29th seed in the second round at 10:00 BST on Thursday.
However, a muscle problem has been exacerbated by playing four matches in seven days in Paris.
The world number 121 hopes to be fit in time to return at Queen's Club next month.
Edmund came through three rounds of qualifying at Roland Garros before beating France's Stephane Robert on Monday to claim his first main draw win at a Grand Slam.
