Based on Tuesday's practice in Voorhees, left winger Taylor Leier will likely replace the injured Michael Raffl on the Flyers' top line Wednesday in St. Louis.
In other developments from practice:
Center Sean Couturier, who hasn't played since Nov. 22 in Florida because of a knee injury, had travel issues and wasn't at practice. GM Ron Hextall said he was hopeful he returns to the lineup Wednesday.
Coach Dave Hakstol said he will keep Brayden Schenn at center for the time being.
Defenseman Nick Schultz, a healthy scratch the last 22 games, will likely return to the lineup Wednesday and replace Brandon Manning.
Goalie Michal Neuvirth had his first full practice since sustaining a knee injury; he will make the three-game road trip but probably won't be ready to play.
Right winger Jake Voracek missed practice because of what the team called a maintenance day. He will be in the lineup Wednesday.
Winger Matt Read (oblique injury) participated in practice. He will also make the road trip but is not likely to play until the Flyers return home Jan. 4 against the New York Rangers.
Defenseman Mark Streit (shoulder) practiced Tuesday but said he needs more time before he is ready to play. He will make the trip to St. Louis, San Jose and Anaheim.
