Novak Djokovic is set to miss Indian Wells and the Miami Open after the United States extended its requirement for international visitors to be vaccinated against Covid-19.
Proof of vaccination will be required to enter the country until at least April 10 but Serbia’s Djokovic has previously said he is unvaccinated.
Indian Wells and the Miami Open - two of the most prestigious tournaments on the tennis calendar outside the Grand Slams - start on March 6 and 20 respectively.
Former world number one Djokovic, 35, is currently in Australia - 12 months after he was deported from the country before the Australian Open because of his vaccination status.
Australia dropped its vaccine requirements in July and Djokovic’s three-year visa ban was overturned in November.
