Kevin Anderson has withdrawn from next week’s US Open due to a right knee injury.

The 33-year-old South African, who has been limited to five tournaments this season, was aiming to return to action for the first time since Wimbledon. After also struggling with a right elbow injury earlier in the year, Anderson was bidding to add to his 11-4 record in the coming fortnight in Flushing Meadows.

Anderson reached his first Grand Slam final at this event in 2017 and has compiled a 22-9 record at the hard-court Grand Slam since his main draw debut in 2010. The six-time ATP Tour titlist will be replaced in the draw by lucky loser Paolo Lorenzi of Italy.
