Spanish tennis star Rafael Nadal concedes he might not be able to play 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.
"I will not be at the best level in any of the categories," Nadal said.
"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."
Nadal's Spanish team-mate David Ferrer acknowledged last week that the 14-time grand slam champion's fitness situation was "delicate".
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 players also missing.
Roger Federer is out due to a knee problem, Wimbledon finalist Milos Raonic withdrew citing fears over the Zika virus while Australia's two top-ranked men Nick Kyrgios and Bernard Tomic are both absent after falling afoul of Australian officials.
