Stress fracture ends Radwanska's season
Poland's Agnieszka Radwanska will not play again this season and could miss the Australian Open in January because of a stress fracture to her foot.
"I'm done for this year with a very serious injury, a stress fracture," the world number 11 said after losing her first round match in Beijing.
"It's a complicated injury and there's some chance it won't be healed in time for Australia. We will see and I just have to hope I will be ready.
"I have an excuse for losing today. I just realized how serious the injury was just before I came to Asia to play in Tokyo and Beijing. I'll be pulling out for the rest of this year."
Radwanska, 21, said was not sure where she picked up the injury but it clearly hindered her performance in the Chinese capital where the sixth seed lost to German Angelique Kerber 7-5 6-7(3) 5-7.
"I'm probably not going to make a top 10 finish as I won't be playing the in last two tournaments of the year and the other girls are playing well," she added.
"It's been a good year and I think I should finish in the top 15."
