World No.1 Novak Djokovic has tested positive for the coronavirus after organising exhibition matches without social distancing.
Fellow stars Grigor Dimitrov, Borna Coric and Viktor Troiki all failed Covid-19 tests following the events in Belgrade and Zadar.
Now reigning Wimbledon and Australian Open champion Djokovic has tested positive to throw the planned return of tennis in August in question – and cause further controversy over his Adria Tour matches.
He said he has not shown symptons but will now self-isolate for 14 days. Andy Murray and Dan Evans were among the players to criticise the Serb's exhibition matches.
