RIO DE JANEIRO (Reuters) - Spain's Rafael Nadal has confirmed he will compete in all three tennis events at the Rio Olympics despite being not at his best after being sidelined with a wrist injury since May.

There were doubts whether the 2008 gold medallist, who withdrew from the French Open and missed Wimbledon, would recover in time to compete at the Games.

World number five Nadal, who is due to be Spain's flag bearer, will compete in the singles event and also take part with Marc Lopez in the doubles and Garbine Muguruza in the mixed doubles.

"I'm going to do as best as possible in every event I play in," Nadal said.

Swiss players Roger Federer and Stan Wawrinka have pulled out due to injury problems while Wimbledon finalist Milos Raonic withdrew citing fears over the Zika virus.
