Juan Martin del Potro has been ruled out of Wimbledon after fracturing his right knee cap during his first-round win at the Fever-Tree Championships at Queen's Club.
The world No 12 pulled out of the Wimbledon warm-up tournament on Wednesday evening after a slip during his first-round win over Denis Shapovalov resulted in his right knee swelling up, and tests have confirmed the Argentinian's worst fears after showing a fracture of his right knee cap.
A statement released on Twitter by Del Potro's agent, Jorge Viale, read: "The medical studies done last night in a clinic in London show that Juan Martin Del Potro has suffered again a fracture in the right patella.
"After consultation with his doctor, Angel Cotorro, it has been determined that it will require surgery. This will take place in the next couple of days with a date and location to be determined. We will keep you informed."
Del Potro has been notoriously unlucky with injuries during his career and this is the second time in less than a year that he has fractured the same kneecap.
The first incident came in a fall at the Masters tournament in Shanghai last October. He initially returned in February but was then sidelined again with further pain until May and has played just five tournaments all season.
