Rafael Nadal has conceded he's not yet sure 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 missed Wimbledon.
Nadal says he won't be at his best level in any of the categories as he hasn't competed for two months and he hasn't trained a lot.
He says he will train a few days in Rio to see what he can do and then decide what is best, to be more positive for him and the team.
Nadal is due to carry Spain's flag in the Olympic opening ceremony on Saturday morning.
