http://www.tennis-x.com/xblog/2014-07-31/16512.phpLi Na announced today that her ailing right knee is not fit enough for the hardcourts this summer, so the Australian Open champion has withdrawn from Montreal, Cincinnati and the US Open.
On Facebook, she posted, “I wanted to let all of my great fans know that unfortunately I am going to have to withdraw from the upcoming WTA events in Montreal and Cincinnati, as well as the US Open. Since March, I have been struggling with my knee and it is just not where I need it to be in order to play at the highest level. My medical team has advised me that I need to take some time off to rest my knee so it heels. I look forward to getting back on the court this fall in Wuhan and Beijing.
