Chinese tennis star Li Na is set to announce her retirement from the professional women's circuit on Sept. 19, according to a microblog post from China's state media. The claim was first made on the official Sina Weibo account of the sports channel of China's national broadcaster CCTV, which claimed that Li, currently ranked No. 3 in the world, is stepping away from the game due to health reasons. The announcement will reportedly be made by IMG, her management company, in her hometown of Wuhan, the capital of central China's Hubei province, on the same day the city launches the inaugural Wuhan Open. The 32-year-old Li has been dogged by retirement rumors after splitting from her coach Carlos Rodriguez in July and being forced to sit out this year's US Open with a knee injury that has bothered her since March.
