World number one Novak Djokovic will return to the court next month for a new tour in the Balkans.
The spread of coronavirus - and the subsequent suspension of the ATP Tour - means Djokovic has not played since beating Stefanos Tsitsipas in the final of the Dubai Tennis Championships in February.
The ATP Tour will not resume until August at the earliest, but Djokovic has confirmed he will participate in a new tournament that is launching in his native Serbia.
The Adria Tour will be held in four countries - Serbia, Croatia, Montenegro and Bosnia-Herzegovina - with events on June 13-14, June 20-21, June 27-28 and July 3-4.
Djokovic, who turned 33 on Friday, will play in each leg of the series and will face Bosnian Damir Dzumhur on July 5 in a final exhibition match in Sarajevo.
He wrote on Twitter: "I'm proud to officially share the news that the #AdriaTour will be held across the #Balkans 13 June - 5 July kicking off with a tournament in Belgrade. Very grateful we could make this happen to play and support humanitarian projects across the region."

Tournament organisers said the aim of the series is to raise money for "humanitarian projects across the region" as well as helping tennis players get back in shape during the ATP Tour suspension.
As well as Djokovic, Austria's world number three Dominic Thiem has also signed up, as have Bulgarian Grigor Dimitrov and Serbia's Viktor Troicki.
Organisers said tickets will be sold to fans if "the presence of the audience is allowed".
