• Argentinian lashed out at Quinn Sullivan in 2-2 draw

Lionel Messi has been fined for slapping an opponent during a Major League Soccer game. The 39-year-old Inter Miami forward lashed out at Quinn Sullivan of Philadelphia Union during their match on Wednesday, catching the midfielder around the back of the head.

The Argentinian appeared to be angry Sullivan had elbowed him after he had played the ball, with the referee intervening before the situation could escalate. The match at Subaru Park finished 2-2.

• 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.
