In Tennis, World number one Novak Djokovic has withdrawn from this week’s Indian Wells Masters event with the Serb unable to enter the United States.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 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.
