Jannik Sinner and Jack Draper out of US Open as injuries take their toll

• World No 1 makes difficult decision' to miss slam

• Draper still recovering from bone bruise in left arm

Jannik Sinner will miss the US Open with a right knee injury. The world No 1 has not played a match since beating Alexander Zverev last month to successfully defend his Wimbledon title, missing the Masters 1000 events in Canada and Cincinnati. Great Britain's Jack Draper is also out of the event.

The news comes a day after his great rival Carlos Alcaraz, whom the Italian lost to in the final in New York 12 months ago, revealed he will make his comeback at Flushing Meadows after four months out with a wrist injury.
