Two-time mixed doubles champion Jamie Murray says he believes Wimbledon will be cancelled.
The All England Club board will hold an emergency meeting on Wednesday to discuss the fate of the 2020 tournament.
The grasscourt season lasts only six weeks and Wimbledon is staged when daylight hours are the longest in Britain. The club has acknowledged the short window available to it and ruled out playing without spectators.
The French Open has been postponed from May to September.
The brother of two-time Wimbledon singles champion Andy Murray was asked whether he thinks a cancellation is more likely than a postponement. He told BBC Radio 4: “I think so. I think for them it is difficult to move the tournament back for many reasons, because you are running into other tournaments.”
Earlier, the organizers of the Swiss Indoors tennis tournament in Roger Federer’s hometown of Basel announced that the ticket sales will start on schedule on Thursday.
The tournament is due to run from Oct. 26 to Nov. 1. Organizers say tickets will be refunded “should the coronavirus crisis continue and the Swiss tennis highlight not take place.”
The ATP Tour is currently suspended until at least June.
Federer and his wife donated 1 million Swiss francs ($1.04 million) last week to help families in need in his home country during the pandemic.
Federer is a 10-time champion at the Swiss Indoors and will turn 39 before this year's tournament. He was twice a ball boy at the event and made his debut as a player in 1998 when he was 17. He lost in the first round to Andre Agassi.
Federer posted footage on his social media accounts on Monday of him practising trick shots in his rehabilitation after surgery on his left knee in February.
