Wimbledon is set to start in London on June 29, but the continuing spread of the virus has caused havoc with the sporting schedule and the grass-court Grand Slam could be the next major event to be delayed.

"The AELTC can confirm that it is continuing a detailed evaluation of all scenarios for The Championships 2020, including postponement and cancellation, as a result of the COVID-19 outbreak," an All England Club statement said on Wednesday.

"An emergency meeting of the AELTC Main Board is scheduled for next week, and in preparation we are communicating closely with the LTA, and with the ATP, WTA, ITF and the other Grand Slams."
