Oh No....

Spain will be without the services of Rafael Nadal when the Davis Cup team travels to Argentina for the final later this month after the World No. 1 confirmed he would not be able to play due to right knee tendonitis.

Nadal had clinched Spain's place in the Davis Cup final with a decisive three-sets win over Andy Roddick of the defending champion U.S. squad in September. He also was a member of the winning 2004 team that defeated the Americans 3-2 in Seville.

"After a long and very positive season, it pains me to miss the two main objectives of the year, the (Tennis Masters Cup in) Shanghai and Davis (Cup) final," Nadal said at a press conference on Tuesday. "This is a difficult time, but I have done everything possible to try and make this final. I am used to playing with pain, but this is a new and different kind of pain, which I can't manage to control."

Nadal retired with a knee injury in his quarterfinal match against Nikolay Davydenko at the BNP Paribas Masters three weeks ago, and afterwards withdrew from the Tennis Masters Cup in Shanghai.

The 22-year-old Mallorcan finishes his career-best season with a 82-11 record and eight titles, including wins at Roland Garros, Wimbledon and the Beijing Olympics. He is guaranteed to finish the season as the No. 1 player in the South African Airways ATP Rankings, ending Roger Federer's four-year reign at the top spot. He is the first Spaniard to finish as the top player in the world.

Spain will be looking to snap Argentina's 13-tie winning streak on home soil when the two teams face off from November 21-23 at Mar del Plata. Spain has won its previous two meetings against Argentina, when they played host in the 1926 quarterfinals and 2003 semifinals.

Spain has won two Davis Cup titles (2000, '04) from five finals, while Argentina is a two-time runner-up.
