Russian Safina has been battling against a back injury

Former world number one Dinara Safina will miss the French Open later this month after taking an indefinite break from tennis.

The 25-year-old Russian withdrew from a match against Victoria Azarenka last month because of a back injury.

She said: "I don't know how long my time out is going to last. I don't want to torture myself and my body anymore.

"I'm just tired of constant questions from my coach in training, 'How is your back? Can you do this exercise?'."

Safina added: " I'm just tired of fighting with myself. At the moment I can't do anything tennis-wise. When I can do certain moves without feeling lots of pain, then I would consider resuming my training.

"Right now I don't care when I might return - this summer during the American hardcourt series, towards the end of the season or next year.

"I'll take as much time as I need."

The right-hander became world number one in April 2009 and stayed there for 26 weeks before falling to 108th because of her back injury problems.

But she has failed to win a singles Grand Slam title having lost out in three finals.
