MADRID, Oct. 25 (Xinhua) -- Spanish tennis star Rafael Nadal, who has been out of action since June, will miss the ATP Tour Finals in London and also next week's Paris indoor event due to his injured left knee, the ATP Tour announced Thursday.

He said in late September that he would not return to the circuit until he was 100 percent fit.
