Rafael Nadal says tennis should set a positive example to the rest of society, and "wait a little bit" before resuming competition.
The 19-time Grand Slam champion does not think tournaments should restart until every single player is able to travel freely and safely.
No tour events will be staged until the end of July - at the very earliest.
And the Spaniard says he currently has little desire to travel to New York in August to defend his US Open title.
"If you asked me if I want to travel to New York today to play a tennis tournament, I will say no - I will not," Nadal, 33, told reporters at a time when the French Open should have been reaching a climax.
