Paris - Spanish tennis superstar Rafael Nadal, out of action since June, will miss the ATP Tour Finals in London and also next week's Paris indoor event at Bercy owing to his injured left knee, the ATP Tour announced on Thursday.
Nadal had hoped to make London and potentially the Davis Cup final, but the world No 4 had been fighting a losing fitness battle.
The former world No 1 has not played a competitive match since his shock loss to unseeded Czech Lukas Rosol in the second round at Wimbledon on June 28.
The 26-year-old Mallorcan has been suffering with Hoffa syndrome, an inflammation of the fatty tissue situated behind the kneecap in his left knee.
He declared in late September that he would not return to the circuit until he was 100 percent fit.
Nadal missed the London Olympics and the US Open, but had hoped he might make the London finals from November 5-12 and the Davis Cup final against the Czech Republic in Prague thereafter.
Both events will take place on hard courts, which are more likely to aggravate existing injuries than Nadal's preferred surface, clay.
