The Spaniard, who has never won the indoor hard court event at the Palais Omnisports in Bercy, said on his Facebook page it had been a tough decision but he was also thinking about his preparations for next year.

"I won't be playing this upcoming week the tournament in Paris Bercy," Nadal wrote.

"It's been a difficult decision to take but I understand that it is what I need to do right now to prepare well for the end of this season and also for 2012.

"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."
