Wimbledon organizers will announce the cancelation of the grasscourt Grand Slam this week due to the coronavirus pandemic, German Tennis Federation Vice President Dirk Hordorff has told Sky Sports.

All England Lawn Tennis Club officials earlier said the June 29-July 12 event would not be played behind closed doors and postponement was not without significant risk and difficulty.

"Wimbledon has stated that they will have a board meeting next Wednesday and will make the final decision there," Hordorff told Sky Sports Germany.

The postponement of the Tokyo Olympics opened up a two-week window in the tennis calendar in July/August but it is less likely that it will be feasible for Wimbledon, which has only two covered courts and cannot be held past late summer.

French Open organizers stunned the tennis world by unilaterally postponing the clay-court Grand Slam at Roland Garros from May until late September because of the pandemic.

The French Tennis Federation (FFT) came under heavy fire from tennis players around the world at the lack of communication as the new dates clashed with several other events already featuring on the calendar.
