Jo-Wilfried Tsonga will miss the rest of the tennis season with a knee injury, ruling him out of France's Davis Cup final against Serbia next month.
The French No. 1 hurt his left knee at Wimbledon earlier this year, and the injury flared up again after last week's Open Sud de France, where he lost in the semifinals to Davis Cup teammate Gael Monfils.
Tsonga, ranked 13th, says he needs "six weeks of complete rest" and does not want to risk aggravating the injury.
He had hoped to play in next week's Paris Masters, a tournament he won in 2009.
The Davis Cup final will be played in Belgrade from Dec. 3-5.
