World number three Rafael Nadal has withdrawn from next week's Toronto Masters due to a nagging knee injury, tournament organisers said today.
The 26-year-old Spaniard, who crashed out of Wimbledon in the second round in June, said he needed more time to recover from an injury that kept him from defending his Olympic title at the London Games.
"Coming to Toronto is always one of the highlights of my season so I'm very disappointed that I can't play there this year," the 11-times grand slam champion said in a statement.
"I was planning on coming to Toronto and did everything I could to be ready but I still need some more time to recover."
Despite winning a record seventh French Open title this year, Nadal has fallen to three in the world rankings and the state of his knees is sure to become a topic of debate leading into the 27 August-9 September US Open, the year's final grand slam.
