General manager Paul Holmgren said Voracek would be reevaluated when the team returns to Philadelphia. Voracek may not play in Tuesday's game against visiting Carolina.
Voracek, who plays on the top line with Claude Giroux and Michael Raffl, returned to the bench in the third period but was not inserted back into the lineup.
If Voracek is sidelined, "it's a loss, for sure," coach Craig Berube said. "He's a good player, one of our better players. If that happens, guys have to step up and play."
In 50 games, Voracek has 14 goals and 35 points. He has had eight multi-point games in the last 19 contests, collecting nine goals and 21 points in that span.
Goalie Steve Mason, who has a 4.55 goals-against average in his last four starts, is expected to face the Hurricanes on Tuesday. . . . Defenseman Marc-Andre Bourdon, sidelined all season with post-concussion syndrome, was assigned to the Phantoms of the AHL. . . . Kimmo Timonen left the ice in the third period, but Berube said that it was a skate issue and that the veteran defenseman was not injured.
The Islanders had 43 shots, the second-most by a Flyers opponent this season. . . . Mark Streit had four of the Flyers' 22 blocked shots. . . . Read had the sixth multi-goal game of his career. . . . Wayne Simmonds scored his 99th career goal.
