(Reuters) - World number one Rafa Nadal has withdrawn from the upcoming Basel indoors tournament due to a knee issue, the Spaniard has said. With the ATP Finals coming up next month, Nadal said on his Facebook page he had made the decision to pull out of next week's Basel tournament after getting medical advice. "I sadly announce that I have to pull out of the Swiss Indoors Basel, after seeing my doctor in Spain just after landing from Shanghai," said Nadal on Tuesday. Nadal, 31, leads Federer by 1,960 points in the rankings but the 36-year-old Swiss can gain 500 points if he wins at Basel with another 1,000 up for grabs at the Paris Masters. Nadal and Federer have each won six titles this year, splitting the four grand slams between them.
