Yeah, competing in the Olympics without fans would be weird -- but it's not a crazy idea ... this according to track legend Jackie Joyner-Kersee who says "it would be just like practicing."
"I hope it doesn't come to that but I also want out nation and our world to be safe," JJK told us in New York City.
Of course, everyone is freaking out about the Coronavirus -- and with multiple major pro sports organizations are kicking around the idea of banning fans from attending events in person.
With the 2020 Olympic Games just around the corner in Tokyo, people are wondering if there will be a no-fan policy there as well.
