Andy Murray is a doubt for the French Open after suffering a lower back problem that forced the world number two to retire from the Italian Open on his 26th birthday on Wednesday.
_0">Murray retired from the contest against Spain's Marcel Granollers moments after leveling the second-round match by winning the second set having already had treatment on court.
"I pulled out because there is a good chance I wouldn't be playing tomorrow. We'll have to wait for Paris. I'd be very surprised if I were playing in Paris," he said.
"I need to make plans and see what to do. Tonight I'll speak with the physio and come up with a plan for the next few days and then make a decision on Paris after the next five days."
The French Open starts on May 26.
"I'll need to take some days off and see how it settles down, but a few days can make a difference," Murray was quoted as saying on the official ATP website (www.atpworldtour.com).
"I'll try and get it sorted but it has been an issue for some while," said Murray. "So I want to make sure that it's something that I can sort out. It's not enjoyable to play now."
Murray, who lost the opening set 6-3 to Granollers, won the second 7-6 but retired having needed treatment on court after the third game of the second set with the Spaniard leading 2-1.
