Canada's Bianca Andreescu has decided not to compete at the Tokyo Olympics due to ongoing concerns around the COVID-19 pandemic.
The former US Open champion is the latest big-name player to opt-out of the Games, which will be held under strict COVID-19 safety protocols with no fans in attendance.
Rafa Nadal, Dominic Thiem, Stan Wawrinka, Nick Kyrgios, Serena Williams and Simona Halep have already announced their decisions to skip the pandemic-delayed Olympics.
"I have been dreaming of representing Canada at the Olympics since I was a little girl," world No.5 Andreescu said on Instagram.
"But with all the challenges we are facing as it relates to the pandemic, I know that deep in my heart this is the right decision to make for myself."
The 21-year-old, who last competed at Wimbledon where she lost in the first round, said she looked forward to representing Canada in Fed Cup ties and at the 2024 Paris Olympics.
Andreescu became Canada's first Grand Slam singles champion with her 2019 US Open triumph, but has had a run of injuries starting with a knee problem at that year's WTA Finals in Shenzhen.
Fellow Canadian Denis Shapovalov, who reached this year's Wimbledon semi-finals, also said last month that he would not compete in Tokyo.
