April 14 (Reuters) - Jack Draper ⁠vowed to work his way out of his injury woes ⁠after being forced to retire with a right leg problem ‌midway through his first-round match against Tomas Etcheverry at the Barcelona Open on Monday.

The 24-year-old Briton, who returned to action in February after six months out due to ​a niggling left arm injury, pulled up while ⁠trailing 1-4 in the ⁠deciding set of his meeting with Argentine Etcheverry to cast doubts on ⁠his ‌fitness for the clay season.
