Serena Williams has ruled herself out of the two upcoming WTA tournaments in China due to a right shoulder injury.
Williams announced her withdrawal from the Wuhan Open and China Open in Beijing just hours before the draw ceremony took place for the Wuhan Open.
Williams’ decision to pull out of both tournaments casts doubts over whether she will be fit enough to participate in the season-ending WTA Finals in Singapore next month.
"I have been practising and playing but my shoulder is still not fit for tournament play," the 34-year-old said in a statement. "I am disappointed that I will not be able to compete at the Wuhan Open or the China Open due to continuing issues with my right shoulder."
The world number two was hampered by the same injury earlier this year and it resulted in her missing the Rogers Cup in July and the Cincinnati Open in August.
Williams’ season has been plagued with injuries and to make things worse, she was dethroned as the top-ranked player by Angelique Kerber, who won two grand slam titles this year – at the Australian Open and US Open – and a silver medal at the Olympics in Rio de Janeiro.
