The reigning Olympic champion has announced that he will not be taking part in London 2012 due to a lack of fitness.
Rafael Nadel had expected to be the flag carrier for the Spanish team at the opening ceremony of the Games but it has been confirmed that he (will) not be travelling to London.
"It is one of the saddest moments of my career. I am not in condition to compete in the London Olympics and therefore will not travel as planned with the Spanish delegation to take part in the Games," said the player.
"I have to think about my companions, I can't be selfish and I have to think of what's best for Spanish sport, especially tennis and Spanish players and give fellow sportsmen with better preparation the chance to compete.
"I've waited until the final moment of my preparation and my training, but I cannot do it."
Nadal has not played a competitive match since he was beaten in the second-round of Wimbledon against Lukas Rosol.
However, the news could clear the way for home favourite Andy Murray to win gold, although Serbia's Novak Djokovic, who is seeded number one, is still planning to take part.
Visitors staying at luxury suites in London who have tickets for the Olympic tennis will be hoping that Murray will again take on Roger Federer in the final.
The recent Wimbledon showdown between the two players resulted in a win for the Swiss player 4-6 7-5 6-3 6-4 on Centre Court and a return to top of the world's ranking.
