WATCH: Djokovic, Puig react to Tokyo 2021 move

News is moving fast these days in an unprecedented period in sports history. Last week, the Olympic Games announced that Tokyo 2020 would not take place. This week, new dates for 2021 are already set, with the Games scheduled for July 23 to August 8.

Reigning gold medalist Monica Puig had an immediate positive reaction.

"Sports will always be around and we will be back competing and fighting again soon, but I am proud of the decision to put human lives and health first above everything," the Puerto Rican wrote.

Stan Wawrinka posted an epic throwback to the 2008 Olympics, where he and Roger Federer won gold together.

Novak Djokovic expressed sadness, but is already looking forward to next year. He won a bronze medal in singles in 2008.

And Petra Kvitova, who would pick up a bronze medal in Rio, agreed it is the right decision.

In the grand scheme of things, health is first, and when you take a look at the Olympic sports impacted by Tokyo's move, tennis might be one of the least affected since players train year-round and have their chances at Grand Slams and titles regularly—not to mention most athletes career spans include multiple Olympic Games.

Any further pro tennis in 2020 is totally up in the air as Wimbledon is expected to announce its cancellation on Wednesday.
