Nick Kyrgios has withdrawn from the US Open because of the coronavirus pandemic, saying it “hurts me at my core” to miss the tournament.
Fellow Australian and women’s world number one Ashleigh Barty withdrew earlier this week.
In a video on social media, Kyrgios, 25, also criticised the behaviour of some players during the pandemic.
The world number 40 added: “It hurts me at my core not to be out there competing in one of the sport’s greatest arenas, Arthur Ashe Stadium.
“But I’m sitting out for the people, for my Aussies, for the hundreds and thousands of Americans that have lost their lives, for all of you. It’s my decision.”
Last month, the Australian said the United States Tennis Association (USTA) was “selfish” for staging the New York tournament, which starts on 31 August.
The event is set to be held without fans at Flushing Meadows with players having to follow strict measures.
