Rafael Nadal has conceded 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 and then missed Wimbledon.
"I will not be at the best level in any of the categories," Nadal told journalists 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 for me and the team," he said.
World number five 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 Roger Federer ruled out by a knee problem and Milos Raonic withdrawing citing fears over the Zika virus.
