Serena Williams' 186-week reign at the top of the WTA rankings

Serena Williams announced Friday that she has pulled out of two forthcoming tournaments in China citing an ongoing shoulder injury.

"I am disappointed that I will not be able to compete at the Dongfeng Motor Wuhan Open or the China Open due to continuing issues with my right shoulder," Williams said in a statement.

Williams has not been seen on court since the US Open earlier this month, where she was knocked out by Czech Karolina Pliskova in the semi finals and lost her long-held position as world number one to eventual winner Angelique Kerber.
