World pairs champions Deanna Stellato-Dudek and Maxime Deschamps of Canada withdrew from the prestigious Grand Prix Final on Monday because Deschamps is recovering from an illness and unable to compete.

Rebecca Ghilardi and Filippo Ambrosini of Italy will replace them. The select competition begins Thursday at the Patinoire Polesud in Grenoble, France with the pairs short program, and the medals will be decided after the pairs free skate on Friday night.

The Grand Prix Final is traditionally a preview of the world championship, which takes place in March in Boston.

Stellato-Dudek, who is from Chicago but representing Canada, and Deschamps, from Vaudreuil-Dorion, Que., were among the favourites for the Grand Prix Final, which brings together the top six skaters and pairs in each discipline to conclude the Grand Prix season.

The couple were third at the Grand Prix Final last year, then swept the Grand Prix of Finland and defended their Skate Canada title in front of home fans this season.

Ghilardi and Ambrosini were third at the Grand Prix of Finland and Grand Prix de France this season.
