Jack Draper will not play again this season because of the arm injury that forced his withdrawal from the US Open.
The 23-year-old British number one left New York before his second-round match because the discomfort in his arm had become too much.
Draper, ranked seventh in the world, had not played singles since Wimbledon because of bruising on his upper left serving arm, although his team were confident a scan taken before the US Open suggested a full recovery.
But after beating the Argentine qualifier Federico Agustin Gomez in the first round, Draper flew home and now says he must rest and sit out the remainder of the season.
