Andy Murray thinks it is unlikely he will make the French Open after pulling out of the Italian Open because of a back injury.
The British number one admitted he would be “very surprised” if he was fit enough to turn out at Roland Garros, which starts in under two weeks.
“I would be very surprised if I was playing in Paris," he told reporters after the match.
"I need to make a plan as to what I do. I'll chat with the guys tonight and make a plan for the next few days then make a decision on Paris after the next five days.
"I want to make sure it goes away. It's been a problem since the end of 2011 but it got bad during last year's clay season."
It was a miserable 26th birthday for Murray as he was forced to retire from his second round clash with Marcel Granollers after levelling the match.
Murray has only retired hurt once before in his career, which came exactly six years ago on his 20th birthday after snapping a wrist tendon while playing at the Hamburg Masters.
The US Open champion looked out of sorts for much of the match and Granollers took the first stanza 6-3.
Murray was forced to take treatment after the third game of the second set when he looked on the brink of being dumped out after falling 4-1 behind.
However, the World number two showed great determination to fight back and eventually levelled the match by taking the second set tie-break.
Not playing in Paris will be a huge blow to him, especially as this was seen by many – including Boris Becker – as being his best chance yet to win the clay court Grand Slam.
