Novak Djokovic will not be playing at the 2022
US Open due to not complying with the rules of entry into the US.
Djokovic is an unvaccinated foreign individual and as such can't enter the US. The country requires foreign nationals to be vaccinated with two doses in order to enter the country in order to protect public safety. The policy has been questioned by many locally and internationally but it's in place at least till the end of this year.
Djokovic could have avoided all of this by getting vaccinated but he categorically ruled that out early in the year. In the end, he won't participate due to a choice he made and a lot of tennis player seem okay with that. Some were vocally opposed to it such as former player Mardy Fish who apologized to Djokovic on social media after the news came out.
He wrote:
"Politics win again. Sorry Champ."
