After recovering from knee surgery, Briton Kyle Edmund withdrew from the U.S. Open 2021 and provided a chance for Denis Kudla to play in the US Open main draw.

Former Australian Open semi-finalist Edmund underwent surgery for persistent knee problems in March and still hasn't fully recovered.

The 26-year-old player who reached the semi-finals at Melbourne Park in 2018, has not participated in a competitive game since losing in the first round of qualifying in Vienna last October.

Edmund's subsequent ranking dropped from a career-high 14th to 102nd in the world.

World number 90 Kudla replaced Edmund in Flushing Meadows, and the final Grand Slam of 2021 will start in New York on 30 August.

Edmund's withdrawal follows Roger Federer's withdrawal. He declared before this week that he will be out for several months because he needs more knee surgery.

This year, a 40-year-old Swiss only participated in one of the Grand Slam tournaments and reached the quarterfinals at Wimbledon earlier last month.
