Nadal unsure of fitness
Rafael Nadal has admitted that he is not yet sure that he will be able to represent Spain at the Rio Olympics as his fitness concerns linger.
The 2008 gold medallist withdrew from the French Open with a wrist injury before also missing Wimbledon.
"I will not be at the best level in any of the categories," Nadal said after arriving in Brazil.
"I have not competed for two months and I have not trained a lot.
"I will train a few days here to see what I can do and then decide what is best, to be more positive for me and the team.
World No. 5 Nadal, who is due to be Spain's flag bearer, was absent from the 2012 Olympics due to injury and, should he withdraw, it would come as a significant blow for tennis at the Games with several other high-profile player also missing.
