Andy Murray says he will “most likely” miss the rest of the season because of his ongoing hip injury.
The British world number two, 30, pulled out of the US Open two days before the tournament began and has not played since Wimbledon in July.
He has withdrawn from October’s ATP Tour events in Beijing and Shanghai and will likely miss the events in Vienna and Paris later that month.
“This is the best decision for my long-term future,” said the Scot.
In a statement posted on social media, Murray said he will begin his 2018 season at the Brisbane International, starting on 1 January, in preparation for the Australian Open, which begins on 15 January, following a “frustrating year on court for many reasons”.
“I’m confident after this extended period of rest and rehabilitation I will be able to reach my best level again and be competing for Grand Slam titles next season,” he said.
“I have a fantastic team working alongside me to help me through this process and appreciate the support from them and all of my fans over this difficult period.”
The three-time Grand Slam champion travelled to New York with the expectation of playing the US Open and practised all week before withdrawing on 26 August.
