Flyers shaking up lines vs. Blackhawks

   Flyers coach Peter Laviolette changed two of his four lines at Friday's practice, and here are the expected units for Saturday's 1 p.m. matinee against the powerful Chicago Blackhawks:

Simon Gagne-Mike Richards-Dan Carcillo.

James van Riemsdyk-Jeff Carter-Ville Leino.

Scott Hartnell-Claude Giroux-Danny Briere.

Darroll Powe-Blair Betts-Ian Laperriere.

   Leino, who performed admirably in the only two games he played since being acquired from Detroit, will return to the lineup, and it appears Arron Asham will be a healthy scratch. Scott Hartnell, who has not scored in 13 straight games _ and in just three of his last 39 contests _ played sparingly in the third period against Boston Thursday but will likely play Saturday.

   Carter, the Flyers' hottest player, will get two new wingers: Leino and van Riemsdyk. Carter has 10 goals in his last 10 games. Hartnell and Briere had been on Carter's line, but those two wingers will be moved to Claude Giroux's unit.

   Laviolette would not name his goalie. With back-to-back games over the weekened (Sunday in New York against the Rangers), it wouldn't be surprising if Brian Boucher started Saturday and Michael Leighton started Sunday. Since the Rangers are in the same conference as the Flyers, Sunday's game is more important.

    Leighton has made 12 straight starts.

   Boucher hasn't started since Dec. 21.
