Novak Djokovic has tested positive for coronavirus.
The men's world number one tennis player confirmed the diagnosis in a statement, reports the Sky News.
In April, Djokovic had revealed he was an anti-vaxxer - and that it could get in the way of his return to competitive tennis once the sport resumes after the coronavirus pandemic.
In a statement, the Serbian said that his wife, Jelena, also tested positive for Covid-19, but his children tested negative.
Djokovic held a tennis tournament last weekend in Croatia, amid the ongoing pandemic - a move which has been heavily criticised after he brought in players from overseas.
