The rescheduled Tokyo Games 2020 may have to be held behind closed doors it is to take place in Japan this year, athletics chief Lord Coe has admitted.
The World Athletics president remained confident the Olympics and Paralympics would take place despite a Times report suggesting they would be cancelled.
"I would love to have fans, noisy and passionate," Coe told the BBC.
"But if the only way we're able to deliver it is behind closed doors, I think everybody is accepting of that."
Coe, who headed the London 2012 organising committee and is also an International Olympic Committee (IOC) member, said, in the event of a cancellation, it was "not a realistic solution" to push back Paris 2024 and Los Angeles 2028 in order for Tokyo to host the Olympics in three years' time.
