BELGRADE, Serbia -- Novak Djokovic's parents defended their son on Wednesday and blamed another tennis player for spreading the coronavirus at a series of exhibition matches hosted by the top-ranked player.

Djokovic and his wife tested positive for the virus on Tuesday. The 17-time Grand Slam champion apologized online for organizing the Adria Tour events, which brought together professional players from various countries to play matches in Serbia and Croatia.

Thousands of spectators attended the matches, and no social distancing was observed.

Djokovic's father blamed the cancellation of the tour on Grigor Dimitrov, one of three other players to test positive in the past few days. There is no evidence to suggest Dimitrov spread the virus to others.

"Why did it happen? Because that man probably came sick, who knows from where," Srdjan Djokovic told RTL Croatia TV. "He didn't test here. He tested somewhere else. ... I think that's not fair.

"He inflicted damage to both Croatia and to us as a family in Serbia. Nobody is feeling well because of this situation."

Dimitrov, a three-time Grand Slam semifinalist from Bulgaria, was the first Adria Tour participant to test positive for the virus. He was followed by Borna Coric and Viktor Troicki.

"We were wrong, and it was too soon," wrote Djokovic, who had previously said he was opposed to vaccination and might not take a vaccine for the virus even if it became mandatory to travel.

Dimitrov played in matches in both Belgrade and at the Croatian Adriatic resort of Zadar. He reportedly arrived in Serbia from the United States and his native Bulgaria. He did not immediately respond to The Associated Press' request for comment while recovering from the infection in Monaco.

NBA player Nikola Jokic, a Serb who plays for the Denver Nuggets, has also tested positive for the coronavirus. He was pictured shaking hands with Djokovic at an exhibition basketball event in Belgrade this month.

Jokic is reportedly recovering in his hometown of Sombor.

Djokovic's mother said both her son and his wife, Jelena, are feeling fine but are suffering because of the widespread criticism.

"It is horrible what is being written, but we are used to it," Dijana Djokovic told the Belgrade Blic daily newspaper.

The coronavirus outbreak led to the suspension of the ATP and WTA tours in March. Plans were announced last week for the sport's sanctioned events to return in August.

The US Open is scheduled to begin Aug. 31 without spectators.
