World number one Novak Djokovic has withdrawn from this week’s Indian Wells Masters event with the Serb unable to enter the United States.
The 22-time Grand Slam winner, 35, had applied for special permission to enter the US because he is not vaccinated against Covid-19.
The US requires international visitors to be vaccinated and proof will be required until at least 10 April.
Djokovic missed last year’s US Open because of his vaccination status.
