Goran Ivanisevic says Novak Djokovic exploring his options for US Open participation

The US vaccine mandate has put Novak Djokovic's participation in the season's last Grand Slam in doubt. In an interview with La Repubblica, the Serb's coach, Goran Ivanisevic, stated that he's trying his best to find a way to ensure he's able to compete in the New York Major.

However, the Croat doesn't think that the rules are going to change any time soon and Djokovic might have to miss the US Open this year.

"Novak will do everything to be there, maybe he will get a special visa. But there are only two weeks. And, personally, I have zero hope that [Joe] Biden will change the rules before the tournament starts."

Novak Djokovic had already missed the Australian Open at the start of the year due to his unvaccinated status and was deported from Australia after his visa was rejected.
