Wimbledon organisers will announce the cancellation of the grasscourt major on Wednesday due to the coronavirus pandemic, German Tennis Federation vice-president Dirk Hordorff has told Sky Sports.
All England Lawn Tennis Club (AELTC) officials earlier said the tournament, which is due to start on 29 June, 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.
"I am also involved in the bodies of the ATP and WTA. The necessary decisions have already been made there and Wimbledon will decide to cancel next Wednesday. There is no doubt about it. This is necessary in the current situation.
"It is completely unrealistic to imagine that with the travel restrictions that we currently have an international tennis tournament where hundreds of thousands of people from all over the world would travel. That is unthinkable."
The AELTC did not respond to a request for comment.
French Open organisers have postponed their Roland Garros tournament 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.
