World number three Maria Sharapova has pulled out of the Beijing Olympics after an MRI scan on her right shoulder revealed two small tears.

Sharapova said her shoulder had been troubling her since she played at Indian Wells, California in March.

After the results of tests in Montreal, the Russian was flying straight to New York to have the injury examined by sports physician Dr David Alchek, who will provide a second opinion and advise her on how much time she should take off.
