Jack Draper pulls out of US Open before second round with arm injury

• Briton returned from injury at Flushing Meadows

• World No 5 announces decision on social media

Jack Draper has been forced to withdraw before his second round match at the US Open due to issues with the arm injury that has disrupted his progress this summer.

Draper, the fifth seed at the US Open, had already missed seven weeks of competition due to bone stress and bone bruising on his left arm and he had not competed since his second round loss at Wimbledon early last month.
