British wildcard Emma Raducanu retired from her Wimbledon fourth-round match for medical reasons as her dream debut came to a heart-breaking end.
The 18-year-old, ranked 338th in the world before the tournament, was trailing 4-6 0-3 to Ajla Tomljanovic when she called on her trainer.
She left the court to receive further treatment, but it was soon announced she would not be returning.
Tomljanovic will face fellow Australian Ashleigh Barty in the quarter-finals.
"I am actually shocked because Emma must be hurt if she came to the decision to retire," Tomljanovic said.
"I am really sorry for her, I wish we could have finished it.
