Lausanne (Switzerland), Jul 13 (Tennis news) Tennis icon Roger Federer on Tuesday announced that he is pulling out of the upcoming Tokyo Olympics owing to a knee injury.

The Olympics, in which on-site spectators will not be allowed owing to the COVID-19 pandemic, are scheduled to be held in the Japanese capital from July 23 to August 8.

In a statement, he said that he had "suffered a setback" with his knee.

Federer announced the news on Twitter saying that he is "greatly disappointed" on missing out on an opportunity to represent Switzerland in the world's biggest sporting spectacle.

"During the grass court season, I unfortunately experienced a setback with my knee, and have accepted that I must withdraw from the Tokyo Olympic Games," Federer said in the statement.

"I am greatly disappointed, as it has been an honour and highlight of my career each time I have represented Switzerland," he added.

Last week, Federer was knocked out of Wimbledon by Poland's Hubert Hurkacz in the quarter-finals.

Hurkacz beat the legend in straight sets to reach the semi-final. In the first round of the tournament, Federer survived a scare before France's Adrian Mannarino retired due to injury.

In 2020, Federer had two knee surgeries. He even had to withdraw from French Open despite winning three matches to save himself for Wimbledon.
