Almost 12,000 people have signed an online petition urging the United States Tennis Association (USTA) to work with the country’s government to allow Novak Djokovic to compete in the U.S. Open.

This will be in spite of his refusal to take the COVID-19 vaccine.

Djokovic will not be able to participate in the year’s final Grand Slam due to current rules.

Under the rules, travellers seeking to enter the U.S. have to be fully vaccinated and provide proof before boarding flights.

The 21-times major champion won the Australian Open, French Open and Wimbledon titles in 2021.

But he was unable to defend his Melbourne Park crown this year after being deported from Australia over his vaccination status in January.

“There is absolutely no reason at this stage of the pandemic to not allow Djokovic to play at the U.S. Open 2022,” said thechange.orgpetition, which was launched on June 21.

“(The) US Government and USTA must work together to allow him to play … MAKE IT HAPPEN, USTA!”

The Serb retained his Wimbledon crown with a win over Australia’s Nick Kyrgios earlier this month.

He had in February said he was prepared to miss Grand Slam tournaments rather than take the COVID-19 vaccine.
