French Open [ Images ] champion and top seed Juan Carlos Ferrero [ Images ] has pulled out of next week's CA Trophy due to injury, becoming the latest big name to withdraw from the indoor Vienna [ Images ] tournament.

Earlier on Friday, organisers said that the Argentine trio of Guillermo Coria, David Nalbandian [ Images ] and Gaston Gaudio would miss the tournament.

Spain's Ferrero, a finalist at the U.S. Open, was forced to withdraw with a serious heel injury.

Coria, seeded third, withdrew due to a thigh injury, Nalbandian with hand and stomach problems and Gaudio because of a damaged elbow.

Coria has already qualified for the prestigious Masters Cup in Houston from November 8-16 but Nalbandian is still fighting for one of the remaining five places.

The former Wimbledon [ Images ] runner-up stands eighth in the ATP Champions Race, with the top eight players qualifying for Houston.

The top seeds in Vienna are now defending champion Roger Federer [ Images ], Carlos Moya [ Images ] and Jiri Novak.
