MADRID -- Rafael Nadal was left off Spain's Davis Cup squad on Tuesday for their World Group quarterfinal against Germany.
The world No. 1 has been struggling with tendinitis in his knees since being knocked out of the French Open last month and was forced to miss Wimbledon.
Spain captain Albert Costa called up Fernando Verdasco, Tommy Robredo, David Ferrer and Feliciano Lopez for the match on clay in the Puerto Banus bullring in Marbella on July 10-12.
