Former World No. 1 Dinara Safina has no chance of making a comeback from injury and will soon announce her retirement, according to big brother Marat Safin.
Safina, 25, has not played since early May because of persistent back pain. She announced in August that she would not play again this year.
"I don't know how long my time out is going to last because I don't want to torture myself and my body anymore," the Russian said then.
But brother Marat said she had quit for good.
"If you recall, Dinara first suffered the injury in Beijing two years ago," the former men's World No. 1 was quoted as saying on Saturday by Russian media.
"She had tried several times to make a comeback but it only caused her more problems.
"Now she must think of herself, not if she could play again, but just to live a normal life. She must continue with her therapy, but would not be able to play again.
"She will make an official announcement, but being her brother, I think she has no chance at all of making a comeback."
