Roger Federer withdrew from the Paris Masters on Monday in order to "pace" himself for the next year, while Marin Cilic and Jo-Wilfried Tsonga reached the second round.
World number three Federer claimed his 10th Basel title on Sunday but decided to skip the final Masters event of the season at Bercy Arena.
"I am extremely disappointed to have to pull out of the Paris Masters," he said in a statement.
"I have to pace myself since I want to play as long as possible on the ATP Tour.
"I am sorry for my French fans who I will see next year at Roland Garros."
"I just don't know if I should play next week. I'll figure it out with the team."
