PARIS (AFP) - A tearful Jelena Dokic was left hoping on Friday that the latest painful twist in her life story of turmoil will not mean another prolonged absence from tennis. The 26-year-old Australian was poised for a famous French Open victory over Russian fourth seed Elena Dementieva before she was forced to concede the second round tie due to crippling back pain which left her barely able to walk. Dokic, playing her first Roland Garros in five years after her well-documented personal and professional strife, raced through the first set 6-2 against the 2004 runner-up and was 2-2 in the second when disaster struck. Running down a Dementieva service, she pulled up, ramrod straight, holding her lower back and wincing in pain. As she wept courtside, she was allowed a medical timeout and when she returned to Court One she even managed to break to lead 3-2. But by this stage she was reduced to walking pace on the baseline and, after losing the next two games, she shook hands with the Russian. "It was very painful, and I just hope it's not too serious," said the heartbroken former world number four. "I felt like I had the match in my hands. I felt like I probably played the best tennis that I've played this year. It's very disappointing. "I just hope it will be okay and it won't take too much time for it to get better." Dokic won sympathetic applause from the Court One crowd while even Dementieva attempted to console her stricken opponent. "Nothing like that has ever happened to me except when I rolled my ankle at the Australian Open, so obviously it's not my time at the Grand Slams," added Dokic. "But it happens. I'm not 15 anymore, so it's time to take more care now and I just really, really hope it's nothing serious." Dokic was taking part in her first French Open since 2004 having made an emotional run to the Australian Open quarter-finals earlier this year when she was ranked 187 and with her career and life seemingly in a tailspin. She won her opening round match on Tuesday, coming back from a set down to defeat Slovenia's Karolina Sprem 3-6, 6-1, 6-2. It was a remarkable performance, given the latest turmoil involving her estranged father Damir, who has been charged with threatening the Australian ambassador to Serbia and illegal possession of firearms. Dokic, a former world number four but now ranked at 80, won more than three million US dollars in prize money in the first stage of her career, when she was a teenage prodigy. But she lost the money when she split from Damir, who she blames for her downfall, and was reportedly sleeping on the floor of a Melbourne apartment as she prepared for this year's Australian Open. Ironically had she won on Thursday she would have faced compatriot Samantha Stosur for a place in the last 16. The 30th-seeded Stosur beat Belgium's Yanina Wickmayer 6-3, 4-6, 6-4 while Jarmila Groth saw off Mariana Duque of Colombia 6-2, 7-6 (11/9). However, Australian teenager Olivia Rogowska was knocked out by Ukraine's Kateryna Bondarenko 4-6, 7-5, 7-5.
