Novak Djokovic will have to steel himself for another half-baked season after the US extended its ban on non-vaxxed foreigners entering the country.

The sanctions on the un-jabbed will now last until April 10 – meaning that the Serb who has refused to ever get a vaccination will be out of luck for the Indian Wells and Miami Masters in March.

Djokovic made do without a trip to America last season also due to COVID restrictions and his anti-vaxx attitude.

He is currently competing in Adelaide after gaining entry last week to Australia despite being deported for his no-vaxx status a year ago.

The 35-year-old is hoping to build towards a run at a 10th Australian Open title starting mid-month in Melbourne.
