(Reuters) – Olympic silver medallist Marketa Vondrousova has withdrawn from the Summer Olympics in Paris due to a hand injury, the 25-year-old Czech woman said on Monday.

Vondrousova reached the women’s final in Tokyo three years ago as an unseeded player, where she lost to ninth-seeded Swiss Belinda Bencic. The Swiss, who gave birth to a daughter in April, will not be in Paris to defend her title.

“I am very sorry, but due to health reasons I will not participate in this year’s Olympic Games in Paris,” Vondrousova posted on Instagram.

“I hoped until the last moment that I would be able to play at least in doubles, but problems with my hand did not allow me to go on court.”

Katerina Siniakova, who won gold in doubles at the last Olympics and is a nine-time Grand Slam champion in women’s doubles, replaces Vondrousova in singles and Linda Noskova plays doubles with Karolina Muchova.

Vondrousova won her first Grand Slam at Wimbledon last year, becoming the first unseeded woman to win the singles title. But earlier this month, she became the first reigning Wimbledon women’s champion in 30 years to be eliminated in the first round.

Other notable absentees from the women’s tennis tournament at the Games include world number three Aryna Sabalenka, Ons Jabeur and Emma Raducanu, who turned down a wildcard place to represent Great Britain.
