Maria Sharapova pulled out of the Beijing Olympics on Friday with a shoulder injury.

The glamorous Russian withdrew from the WTA Rogers Cup in Montreal on Wednesday.

The MRI scan revealed two small tears in her right shoulder after she pulled a marathon second-round win over Marta Domachowska.

"I'm currently packing up real quick to hop on a plane to New York for a second opinion but I wanted to let you all know first that there is no chance of me competing in Beijing," Maria Sharapova said on her official website.

Sharapova joins a growing list of Beijing casualties, including former world number one and Athens Olympic silver medallist Amelie Mauresmo and fellow French star Mary Pierce.

"The timing is so unfortunate and this makes me more sad than anything."

"After Wednesday's match I knew there was something seriously wrong with my shoulder," she added on the website.

"After taking a few different exams and MRI's, the doctors found two small tears in the tendons of my shoulder.

"There are so many mixed feelings because on Wednesday night they were almost positive there was something wrong with my nerve, which could have ultimately been much more serious.

"But after Thursday morning's tests, for the first time in a while, they were able to give me a different answer and a different problem."

"This is something that needs a lot of time to heal. It really hurts me to say I have to miss the Olympics," she said.

The injury also throws into doubt whether she will be fit for the US Open, which starts on August 25 in New York. [SOURCE: REUTERS, AP]
