The Calgary Flames were perhaps the league's biggest surprise this season, but their playoff hopes suffered a heavy blow with the injury to Mark Giordano.

The Philadelphia Flyers won't feel any sympathy toward their opponents Tuesday night at the Wells Fargo Center as they try to continue their own postseason push.

Giordano had 11 goals and a team-leading 37 assists before suffering a torn biceps on Wednesday that will leave Calgary without the Norris Trophy front-runner for the rest of the season.

After falling 2-1 to the New York Islanders in their first game without their captain Friday, the Flames (33-25-4) did little to fill the void at the blue line before Monday's trade deadline.

"You don't replace Mark Giordano. You just don't do that today," general manager Brad Treliving said Monday. "The urgency to do something, you have to match that with the calmness of not overreacting and all of a sudden doing something that you're making a big mistake.

"To think that Mark's leaving our lineup and we're going to go out and replace him today, that's fool's gold."

Calgary also lost an offensive presence by trading Curtis Glencross to Washington on Sunday in exchange for draft picks. He had nine goals and 19 assists in 53 games.

Mason Raymond could fill that vacancy. The eighth-year winger looked to have regained his scoring form with six points in six games from Jan. 31-Feb. 12, but was held without a point in his last four. He expects to play Tuesday after missing three games following the birth of his daughter.

"It was great, he got to go spend time with his family but as a team we're excited to have him back," defenseman Kris Russell told the Flames' official website. "He brings a lot to our lineup."

Philadelphia (27-25-11) traded away defensemen Kimmo Timonen and Braydon Coburn prior to Monday's deadline, bringing back a second-round draft choice from Chicago and 24-year-old defenseman Radko Gudas from Tampa Bay.

While those moves were aimed toward the future, general manager Ron Hextall believes his team - six points back of Boston for the Eastern Conference's second wild-card spot - is still in position to compete this season.

"I don't look at us right now like we're not a good team," Hextall told the Flyers' official website. "We're a good enough team to make the playoffs and Cinderella runs happen every year ... No one on our side, including the players and coaches, doesn't think we can't make the playoffs. But as an organization we're trying to stay competitive, trying to stay good and grab assets for the future."

Steve Mason stopped 34 shots in Saturday's 4-2 win over the New York Rangers in his first start since suffering a lower-body injury Feb. 8. Mason owns a career-best 2.25 goals-against average, and his .926 save percentage ranks sixth in the NHL.

"(Saturday's game) was an absolute must-win," Mason said. "Everybody in the dressing room knew the situation going in, and I think the guys responded well. We just have to continue pushing forward."

Philadelphia won both meetings last season on the strength of Brayden Schenn's two goals and two assists, and now catches the Flames at the midpoint of a seven-game road trip.

Karri Ramo is expected to start for the Flames. He's allowed one goal in each of the first three games on the trip after yielding at least two in 15 of his first 18 starts this season.
