李娜在微博和官方Facebook专页分别以中英文发布退赛讯息：
我亲爱的球迷朋友们，很遗憾地通知大家，我不能参加即将到来的蒙特利尔网球大师赛，
辛辛那提网球大师赛和美网了。从3月开始，在我需要处在最佳状态时，膝伤又复发了。
我的医疗团队因此建议我休赛几场以助于康复。我期待着到秋天时回到赛场，参加武汉和
北京的比赛！

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.
