- World number two Li Na of China announced that she will miss next month's US Open as she struggles with a knee injury.
"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," Li said in a statement on her Facebook page.
"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."
The 32-year-old, who won the Australian Open earlier this year, her second Grand Slam after winning Roland Garros in 2011, has targeted a return to the court on home soil in late September.
