Juan Martin del Potro hasn't played a match since the summer of 2019 when he went down at Queen's Club with a right knee cap injury. He recently told ESPN that he's still down, but not out.
The 32-year-old has been plagued by injuries for most of his career, first to both of his wrists (totaling four surgeries) and then to his knee. Since turning pro in 2005, it marks his fourth lengthy injury layoff of eight-plus months (June 2019-present, right knee; March 2015-February 2016, left wrist; February 2014-January 2015, left wrist; and January-September 2010, right wrist).
