All men's and women's professional tennis tournaments through June 7 are being called off because of the new coronavirus pandemic.
The ATP and WTA announced Wednesday that the entire clay-court circuit "will not be held as scheduled" - a day after the start of the French Open, also played on that surface, was postponed from May to September.
The tours had said last week they would suspend play until late April or early May.
The tournaments affected by the tours' suspensions include combined men's and women's events in Madrid and Rome.
Also being scrapped are upcoming WTA tournaments in Strasbourg, France, and Rabat, Morocco, along with ATP events in Munich; Estoril, Portugal; Geneva; and Lyon, France.
Both tours also said that their rankings will be frozen "until further notice." The International Tennis Federation also put a halt to its lower-tier events until June 7.
