This year's Singapore Grand Prix has been cancelled due to Covid-19 restrictions, with Formula 1 now weighing up its replacement options.
For the second year running, the event's organisers and F1 agreed that it would not be possible for the Marina Bay venue to host the early October race as entry restrictions to the sovereign island will still be in place in approximately four months' time.
"To cancel the event for a second year is an incredibly difficult decision, but a necessary one in light of the prevailing restrictions for live events in Singapore," said Colin Syn, Deputy Chairman of the Singapore Grand Prix.
"Ultimately, we have to be responsible, cautious and prudent as safety is our number one concern.
"Needless to say, we look forward to the safe return of Formula 1 racing against the spectacular Marina Bay skyline."
Formula One Management stated that it continues "to work with all promoters during this fluid time and have plenty of options to adapt if needed."
One potential venue seen as a viable replacement for Singapore is Istanbul Park, which was initially scheduled to host the Turkish Grand Prix this month – in place of the Canadian Grand Prix - before the race was scrapped due to travel restrictions between the UK and Turkey.
But Shanghai in China is also an option for F1 while the Circuit of the Americas in Austin has reportedly put itself on the ranks to stage a double header, with a first race taking place a week before the US Grand Prix, scheduled on October 24.
Despite the latest news, Formula 1 remains confident of seeing the 2021 campaign unfold over 23 race weekends.
But the whisper in the paddock suggests that Brazil and Japan are also in jeopardy.
