Andy Murray has announced he is unlikely to return to competitive action until the start of the 2018 season due to a hip injury.

Murray began the year as the world number one but has struggled with injury throughout and has not been seen on court since his last eight exit at Wimbledon.

The Scot had hoped to return in time for the ongoing US Open but days before the final Grand Slam of the year confirmed he would not be involved.

The 30-year-old three-time major winner is struggling with a hip injury and says an extended period of rest will be the most effective way to combat the problem.

"Unfortunately, I won't be able to compete in the upcoming events in Beijing and Shanghai, and most likely, the final two events to finish the season in Vienna and Paris due to my hip injury which has been bothering me the last few months," he said.

"Having consulted with a number of leading hip specialists over the last week, along with my own team, we have decided that this is the best decision for my long-term future.

"Although this has been a frustrating year on court for many reasons, I'm confident after this extended period of rest and rehabilitation that I will be able to reach my best level again and be competing for Grand Slam titles next season.

"I will be beginning my 2018 season in Brisbane in preparation for the Australian Open and I'm look forward playing in Glasgow later this year against Roger [Federer] for UNICEF UK and Sunny-sid3up.

"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."

Murray, now the world number two, will likely miss the season-ending ATP World Tour Finals, where he would have been the defending champion.
