BELGRADE -- World number one Novak Djokovic lost one of his two opening singles matches on Saturday at the charity tournament he organised, and his day got worse when news broke that one of the event's four legs has been scrapped due to coronavirus concerns.
Shortly after beating fellow Serbian Viktor Troicki in his opening match, Djokovic said he was disappointed that the Adria Tour's third leg in Montenegro, scheduled for June 27-28, had been called off.
"I am so sad for the Montenegro leg," he told the Balkan nation's Sport Klub television in a courtside interview in front of a capacity 4,000 crowd.
"We tried everything, but the borders are still not open and we don't have time to organise it all."

With 12,251 confirmed cases and 253 deaths related to COVID-19, Serbia is among the countries whose residents are not allowed to travel to its southern neighbour Montenegro.
Earlier on Saturday, Djokovic's younger brother Djordje and the Adria Tour director, released a statement saying the event's board had decided to scrap the Montenegro leg.
Asked at a news conference after his defeat by Filip Krajinovic whether there was an alternative host nation able to replace Montenegro in a fortnight, Djokovic said:
"We are looking at several alternative options and locations which I don't want to reveal at this point.
"We are running out of time so we will know where we stand either tomorrow or the day after."
The second leg will be held in Croatia's coastal resort of Zadar on June 20-21 and the final one in Bosnia's Banja Luka on July 3-4.
