Tsonga lost to Andy Murray in the last eight at Wimbledon this year
Jo-Wilfried Tsonga has pulled out of the Davis Cup final because of a recurring knee problem.
The world number 13 was set to be named in the French team to take on Serbia in Belgrade next month.
Tsonga only returned to action last month after surgery on his left knee, but aggravated the problem at last week's ATP tournament in Montpellier.
Confirming he will be out for the remainder of the season, the 25-year-old said: "My tendon snapped again."
The injury will force the 2008 Australian Open finalist to miss next week's Paris Masters - a tournament where he would have been hoping for a strong showing in order to force his way into the eight qualification places for the ATP World Tour Finals, which will be held at London's O2 Arena later this month.
And his absence will also be a huge blow for the French team as they seek a fourth Davis Cup title and first since 2001. Gael Monfils will probably be their lead singles player, with Michael Llodra, Richard Gasquet and Gilles Simon fighting it out for the second spot.
Serbia, led by world number three Novak Djokovic, will be bidding to lift the trophy for the first time when the final gets under way on 3 December.
