No play was possible in the French Open on Monday as persistent rain prevented any action from taking place at Roland Garros.
Play was due to get under way at Roland Garros at 11am local time (10am BST), with 10 quarter-final slots across the respective men's and women's singles draws still to be decided.
However, the scheduled start time was put back on a number of occasions by tournament organisers due to continued showers, before confirmation at 1:40pm local time that day nine had been abandoned.
A tweet from Roland Garros' official account read: "Due to weather, there will be no matches played at #RG16 today."
The likes of Novak Djokovic and Serena Williams will therefore have to wait until at least Tuesday to play their fourth-round matches, against Roberto Bautista Agut and Elina Svitolina respectively, with a potential scheduling headache now in prospect.
