MADRID -- Defending Olympic tennis champion Rafael Nadal pulled out of the London Games on Thursday with an undisclosed injury
"I am not in condition to compete
in the London Olympics and therefore will not travel as planned with the Spanish delegation to take part in the Games," the third-ranked Spaniard said in a statement.
Nadal's withdrawal will keep an Olympics tennis streak alive, at least on the men's side. No player (male or female) has ever won consecutive Olympic gold medals in singles.
Nadal did not mention any specific injury, but he canceled a charity match in Madrid on July 4 because of tendon problems in his left knee
. He has had recurring knee problems in the past.
Nadal has not played since losing in the second round of Wimbledon to then 100th-ranked Lukas Rosol, one of the most surprising results in the tournament's history.
I guess we don't really know what the problem is and his camp doesn't seem to be forthcoming with the answer.
