Draper was set to join fellow British No.1 Katie Boulter alongside Davis Cup teammate Billy Harris, Lily Miyazaki, Olivia Nicholls and Charles Broom to face Argentina and Australia.

The 22-year-old has also announced that he won’t be available for Great Britain’s Davis Cup tie against Japan on 31 January – 1 February.

In a statement on Instagram, Draper said: “As I work to get on top of my hip injury and get match fit, I have unfortunately been advised not to play in the United Cup.

“While we are positive about competing at the Australian Open this year, I know I won’t be able to jump straight back into a packed schedule as I manage and strengthen my hip… gutted as I was really looking forward to play in the United Cup for the first time.

“Together with Leon (Smith), we have also made the difficult decision for me to sit out of the upcoming Davis Cup match in Japan in order to give me the opportunity post Australian Open to complete the rehab and strengthening of my hip.”

Great Britain begin their United Cup campaign against Argentina on 30 December, followed by a tie with Australia on 1 January.
