Andy Murray: Australian Open in doubt unless 100% fit
Andy Murray says he will compete in the Australian Open only if he is "100% fit" following back surgery.
The Wimbledon champion began his rehabilitation last week after a disc operation last month.
“The rehab process is pretty tedious and long and I don't want to come back too soon and have to start that process all over again”
Murray, 26, will miss the season-ending ATP World Tour Finals in London but wants to be ready for the first Grand Slam of 2014 in Melbourne in January.
"I hope so, but I'm not going to come back unless I'm 100% fit. I've got a long way to go yet," said the Scot.
"I've been in the swimming pool and on the bike a little bit but it's still going to be four or five weeks until I'm back on the tennis court hitting some balls.
"The rehab process is pretty tedious and long and I don't want to come back too soon and have to start that process all over again. I'll only come back when I'm 100% fit and I hope that's at the beginning of the year."
Murray, who received an OBE from Prince William at Buckingham Palace on Thursday, pulled out of the French Open in May because of his back problems.
The world number four recovered in time to become Britain's first male Wimbledon singles' champion since 1936.
