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将不会打北京500系列赛跟上海大师赛
扣掉去年的北京500分跟上海600分
积分将会降至7,660分
Djokovic目前为6,445分，虽然到年底不会扣分压力，但亚洲赛季只参加上海大师赛。
看来球王之争更加激烈了....
