Juan Martin del Potro is unsure if he has played the last match of an injury-hit career after re-fracturing his kneecap during the Queen’s Club Championships, the Argentine has said.
Del Potro returned to competition after a four-month absence at the Delray Beach Open last week but, with his knee heavily strapped, looked unable to move around freely
The 30-year-old has sustained the injury during the 2018 Shanghai Masters tournament when he fell on his right knee while taking on Borna Coric of Croatia in the third round of the competition. He is still recovering from the injury.
