Wimbledon champion Andy Murray has expressed his disappointment at being forced to withdraw from the ATP World Tour Finals in London due to injury.
There had been hope that the Scotsman would be able to compete in the tournament after seeing a specialist regarding his back injury, which required surgery last month.
However, it has been confirmed by the ATP that Murray will play no part in the season-ending competition.
"I'm really disappointed not to be playing this year, I love playing in front of my home crowd, it's a great atmosphere," Murray told reporters. "All the players look forward to competing in London and I'll be doing my best to qualify again for the tournament next year."
Tournament director Andre Silva added: "It's unfortunate that Andy will be unable to play in this year's tournament. He's had a historic year on the Tour and of course he'll be missed.
"We wish him all the best as he continues his recovery from surgery, and we hope to see him back stronger than ever for the 2014 season."
Rafael Nadal, Novak Djokovic and David Ferrer have already qualified for the eight-man competition.
