Dinara SafinaRussia’s Dinara Safina, the former No. 1 ranked tennis player, has no set time frame for returning to competitive tennis. However, she has not given up hopes of making a return to the Sony Ericsson WTA Tour.

Safina has been off the competitive circuit since the 2010 Australian Open. She had severely injured her back during the 2009 summer season, but had continued to play up through the Australian Open, when she was forced to retire in the fourth round while playing against her countrywoman, Maria Kirilenko.

On Friday, Safina publicly revealed the extent of her injury in a blog entry on her official website. “My injury from Australia was pretty bad and takes so long to heal. The problem is that I had it since Cincinnati last year, and since then had been playing all the time while on pain killers. My back was really bad there but I didn’t feel anything the rest of the season until my last match at the Australian Open. After that match, I had an MRI and I had two stress fractures on L5S1 and a rupture on the muscle. That was the worst news I could ever hear from a doctor, but now finally I’m recovering, though not as fast as I would prefer.”

Though her recovery has been slow, Safina has now resumed practicing. She has not announced a time frame for her return. Currently she is in Croatia working with her physio, Tomislav Vrbnjak. “He is really one of the best I’ve ever had in my life and he is really taking the best care of me,” Safina said.

In spite of never winning a major title, Safina took over the Tour’s top spot last year from Serena Williams of the USA. She is currently ranked No. 3, but that will begin to change soon because she is defending a lot of ranking points during the clay court season.
