Nick Kyrgios has withdrawn from the US Open due to injury, the tournament organised have announced.
Kyrgios missed Wimbledon with a wrist injury, while knee and foot injuries kept him out of the Australian Open and French Open respectively.
The 28-year-old's lack of time on the court has seen him slide down 57 places to 92 in the ATP world rankings.
Kyrgios' best performance at the US Open came last year when he reached the quarter-finals before losing in five sets to Russia's Karen Khachanov.
