London: Tennis ace Rafael Nadal has expressed his disappointment after being ruled out of the Barclays ATP World Tour Finals in London with a chronic left knee problem.
The Spaniard has also withdrawn from the Paris Masters as he looks to regain full fitness for the start of 2013.
The announcement hasn’t come as a surprise, with the world number four having not played since his shock second-round loss to Lukas Rosol at Wimbledon in June.
Nadal missed the Olympics and the US Open after revealing he had a partial tear in his patella tendon, and it was always unlikely he would return during the indoor hard-court season.
“It`s disappointing for me to miss the last two tournaments of the season in Paris and London, but it doesn`t come as a surprise,” the Daily Mirror quoted Nadal, as saying.
“I will hopefully resume my tennis practice soon since I am making good progress with my recovery from injury,” he added.
“I am not ready to compete in time for these events so I will continue my recovery in Mallorca and work hard to be back as soon as possible,” he said.
