Novak Djokovic is again set to miss Indian Wells and the Miami Open after United States travel authorities extended the requirement for non-US nationals to be vaccinated.
Although coronavirus rules have been relaxed or removed in many countries, proof of vaccination will be needed to enter the United States until at least 10 April.
Indian Wells and the Miami Open, two of the most prestigious events on the calendar outside the grand slams, begin on 6 March and 20 March respectively.
Djokovic has refused to get vaccinated and was detained in an immigration hotel on arrival in Australia 12 months ago. The 21-time grand slam champion was then deported after his visa was cancelled by the immigration minister, who decided Djokovic’s presence could stoke anti-vaccine sentiment.
The 21-time grand-slam champion then missed last year’s US Open due to his vaccination status but with vaccination against Covid-19 no longer required to enter Australia, Djokovic successfully challenged a three-year ban on applying for a visa and got his season under way in Adelaide this week.
