Nadal's goal to get knee fit for Davis Cup final

MADRID, Spain -- Rafael Nadal pledged to do everything in his power to rehabilitate his ailing right knee in time for Spain's Davis Cup final against Argentina in less than three weeks.

Nadal has tendinitis in his knee and was forced to
pull out of the season-ending Masters Cup in Shanghai, which
begins Sunday. The world's top-ranked player also had to retire from his Paris Masters
quarterfinal against Nikolay Davydenko last week.

"I will try everything to be at the Davis Cup, but my
participation depends on my progress," the French Open and
Wimbledon champion told Marca radio on Wednesday.

"If I am only at 40 percent I won't go. I have a
few days to recover and I will try to train a bit."

The Spanish tennis federation said Tuesday that Nadal
needed a week of rest and treatment. Nadal said he
would have a final test at the start of next week to determine
whether he can represent Spain in Mar del Plata beginning Nov. 21.

Nadal reiterated his criticism of the packed ATP tennis
calendar, saying it was "very badly organized."

"It's very hard to always be at the highest level with a
calendar like that," he said. "I didn't say no to Shanghai, it was my knee. Going there would have been a very big effort."

Nadal will be replaced at the Masters Cup by Frenchman
Gilles Simon, who will play world No. 2 Roger Federer in
the Swiss top seed's opening match.
