Carter missed 11 games because of a broken right foot. Laperriere was sidelined for 10 games because of a concussion. The Flyers have a 2-1 series lead going into Saturday's game.
Carter, who led the Flyers with 33 goals during the regular season, was injured by a shot from teammate Chris Pronger against New Jersey on April 20.
Laperriere was injured two days later in the series-clinching victory over New Jersey, when he blocked a shot with his face.
