Maria Sharapova has announced that a right shoulder injury will force her to miss the Beijing Olympics.
The Russian tennis star defeated Marta Domachowska of Poland 7-5 5-7 6-2 in a second-round match at the Rogers Cup in Montreal on Wednesday on her return to action after Wimbledon.
However, after the match she withdrew from the tournament, citing shoulder problems.
Sharapova announced yesterday that she had torn tendons.
"After yesterday's match I knew there was something seriously wrong with my shoulder,"' she said on her website. "After taking a few different exams and MRIs this morning, the doctors found two small tears in the tendons of my shoulder.
"There are so many mixed feelings because last night they were almost positive there was something wrong with my nerve, which could have ultimately been much more serious.
"But after the tests this morning, for the first time in a while, they were able to give me a different answer and a different problem.
"But on the other hand this is something that needs a lot of time to heal, which really hurts me to say that I have to miss the Olympics."
Sharapova added that she was heading to New York for a second opinion.
