From Nadal's FB:
Hi all, as you know I had to retire from my semifinal match at the US Open and this past Monday I visited my doctor in Barcelona, Spain checking my knee condition.
Although this knee pain is nothing new to me, we have decided together my medical and technical team that I won’t be playing the Asian swing in Beijing and Shanghai. I need to rest and recover my knee as always.
I am very sorry I won’t be able to be with all my fans in China as well as the tournament organisers who have always been so supportive with me and my team.
Nadal將不會打北京500系列賽跟上海大師賽
扣掉去年的北京500分跟上海600分
積分將會降至7,660分
Djokovic目前為6,445分，雖然到年底不會扣分壓力，但亞洲賽季只參加上海大師賽。
看來球王之爭更加激烈了....
