Singapore Grand Prix organizers have made to Formula 1's chiefs that a race behind closed doors on the city's Marina Bay street circuit "is not feasible".
The event was scheduled for September 20th on F1's original 2020 calendar but the heavy logistics associated with setting up a street track leave practically no room for date changes or flexibility.
Formula 1 is working hard to try and rebuild a calendar that would include between 15 and 18 races.
But coronavirus safety measures and regulations implemented in each country coupled with date constraints and race promoters' financial considerations represent major challenges in putting together a comprehensive agenda.
Singapore says it is maintaining an "open dialogue" with F1, but the prospects of racing under the Marina Bay floodlights this year appear bleak.
Furthermore, the event's promoter has already warned that it is "not feasible to conduct the race behind closed doors".
"The Formula 1 calendar for the 2020 season is currently being finalised and Singapore GP has been maintaining an open dialogue with Formula 1, the Singapore Government, and our stakeholders during this time, to assess different possibilities," an event spokesperson said.
"Singapore GP is also working closely with the Singapore Tourism Board and various government agencies on the circuit setup timeline.
"As the street circuit requires considerable temporary infrastructure, sufficient lead time to complete the construction of the various components must be factored in.
"Works typically require three months to complete, and this will be predicated on whether such activities are permitted under the prevailing government regulations.
"We will continue to keep a close watch on developments. Our utmost priority remains the well-being and safety of our fans, staff, volunteers, and all Singaporeans."
