Both the WTA and the ATP tours have extended their suspension until June 7.

The tours were already postponed until April 21 and May 2 respectively.

The new extension means the entire clay-court season is off as well as joint events in Madrid and Rome. The women's tournaments in Strasbourg and Rabat and the men's events in Munich, Estoril, Geneva and Lyon are also postponed.

All the world rankings have been frozen until further notice.

The French Open, due to begin on May 24, had already been called off earlier this week.

In a joint statement, the tours wrote: "The challenges presented by the Covid-19 pandemic to professional tennis demand greater collaboration than ever from everyone in the tennis community in order for the sport to move forward collectively in the best interest of players, tournaments and fans.

"We are assessing all options related to preserving and maximising the tennis calendar based on various return dates for the Tours, which remains an unknown at this time."

The next major event to happen once tennis is underway is Wimbledon which is scheduled to take place on June 29 until July 12.
