Moscow - Russian pole vault star Yelena Isinbayeva will miss the remainder of the indoor season after tearing a muscle in her left leg at the weekend, her coach Yevgeny Trofimov said on Monday.
"Yelena (Isinbayeva) underwent medical testing after suffering the injury," the Allsport agency quoted Trofimov as saying. "Her exact diagnosis is a rupture of the soleus muscle."
"The medics have put her left leg in a plaster cast. Now it's obvious that she will have to miss the remainder of the indoor season."
Following the injury, Isinbayeva on Saturday was forced to put on hold her intended return to competition after a break of more than two years.
The 33-year-old had been planning to participate in the Volgograd Governor's Cup meet this weekend but withdrew after she felt pain in her leg while jogging.
Torimov said that the injury was a recurrence of an old injury, but he added that he remained optimistic that Isinbayeva would be fit in time for the summer athletics season.
"Isinbayeva suffered a similar injury in 2013," Trofimov said. "But after undergoing therapy in Munich, Germany, she managed to win the world championships in Moscow."
Two-time Olympic champion Isinbayeva took a break after winning the 2013 IAAF world championships, and in 2014 she gave birth to her daughter Eva.
Last year she announced she would resume her career in a bid to compete at her fourth Olympics in Rio in August.
But her Olympic dream could be dashed as the International Association of Athletics Federations (IAAF) has provisionally banned Russia from competitions after a World Anti-Doping Agency (WADA) independent commission found evidence of "state-sponsored" doping in the country.
