Jannik Sinner ‘very sad and disappointed’ as knee injury puts him out of US Open

• World No 1 makes difficult decision' to miss slam

• New York has a special place in my heart'

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.

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 from four months out with a wrist injury at Flushing Meadows.
