"World No. 1 tennis player Novak Djokovic's vaccination status appears to again be causing him to miss a significant tournament, possibly two. Organizers of the ATP Indian Wells Masters event, which begins this week in California, confirmed his withdrawal late Sunday.

Djokovic, who is unable to enter the U.S. because he is not vaccinated against Covid, had petitioned authorities for special dispensation, but was evidently unsuccessful in his bid. He will be replaced in the field by Nikoloz Basilashvili."
