NADAL OUT - SIMON IN

World number one Rafael Nadal of Spain said on Monday that he had pulled out of the Shanghai Masters and his place would be taken by France's Gilles Simon.

"I have decided not to compete in the Masters Cup in Shanghai. As I say this is one of the most difficult decisions in my career due to the importance of the event," he said in a statement posted on his official web site.

The 22-year-old had had to pull out of his Paris Masters quarter-final on Friday with a right knee injury.
