Gagne, who will turn 33 on Friday, planned to take a late flight from Los Angeles and arrive in Philadelphia on Wednesday. He said he would be in the lineup Wednesday night against visiting Washington.
"I'll take the red-eye and fly all night," he said. "It's going to be a special game, but I'll try to take all that emotion and try to bring that energy to the game."
Since last season ended, the Flyers have added four players who formerly played in the organization: Ruslan Fedotenko, Brian Boucher, Mike Knuble, and Gagne.
Gagne played for the Flyers from 1999-2000 to 2009-10 - he ranks ninth in franchise history with 259 goals - and was one of their most popular players. He was traded to Tampa Bay in 2010 for Matt Walker and a fourth-round pick in 2011 that turned out to be Marcel Noebels, now a left winger with the AHL Phantoms.
Playing with Los Angeles last season, Gagne was limited to 34 games because of a concussion. He scored seven goals and got his named etched on the Stanley Cup.
Gagne had no goals in 11 games with the Kings this season and was a healthy scratch six times.
Gagne, who said the sale of his Voorhees home is in the works and will be completed March 15, said that he has fully recovered from June neck surgery, but that it was difficult to find a rhythm this season because he was in and out of the lineup.
In 2010, Gagne scored the game-winning goal as the Flyers stunned host Boston, 4-3, in Game 7 of their epic Eastern Conference semifinals. The Flyers overcame a series deficit of three games to none and trailed, 3-0, in the final game.
Gagne has a cap hit of $3.5 million (pro-rated over a shortened season), and the Flyers made cap space in recent days by placing Andrej Meszaros and Jody Shelley on the long-term injured list.
Ilya Bryzgalov declined to comment on Apple's Siri answering the question "Who is the universe?" with his name. In HBO's 24/7, of course, he chirped about the "humongous big" universe. . . . Flyers opponents have scored first in six of the last seven games, including the last four contests.
