This year's Paris Masters will miss World number two Rafael Nadal who pulled out of next week's tournament so as to concentrate on the ATP World Tour Finals in London and the Davis Cup.
On his Facebook account, the Spaniard said that he had withdrawn to prepare well for the end of this season and also for 2012.
The season-ending Tour Finals, at London's O2 Arena, features the top players and Nadal is one of the five who have already qualified for the tournament. Novak Djokovic, Andy Murray, Roger Federer and David Ferrer are the other qualifiers while the chase for the remaining three places in the eight-man tournament is led by Tomas Berdych, Jo-Wilfried Tsonga and Mardy Fish.
After the Tour Finals, Nadal is in line to represent Spain in their Davis Cup final against Argentina in Seville, on 28 November.
However, the 25-year-old has never won the Paris title and admitted that it was a difficult decision to make, adding: I hope I can be back in 2012 to that great event in the most beautiful city in the world, and hopefully try to win it one day.
He last played when he lost to Florian Mayer in the Shanghai Open in mid-October.
