The St. Louis Blues' performance on a western Canadian road trip is not helping their chances of reaching the postseason.
On Friday night, the Blues could be without star Keith Tkachuk as they hope to salvage a win on the swing while looking to avoid an eighth straight road loss to the Calgary Flames.
While Northwest Division-leading Calgary (41-23-6) tries to maintain the third spot in the Western Conference, St. Louis continues to make a push for its first playoff appearance since 2003-04.
The Blues (32-30-9) played themselves into the playoff picture by going 13-6-4 since the All-Star break before losing their first two games on this trip. They opened with a 2-1 shootout loss at Edmonton on Tuesday before falling 3-0 at Vancouver on Thursday.
"We have scratched and clawed and battled our way back into this picture," coach Andy Murray told the Blues' official Web site. "We're going one game at a time."
The latest setback, however, left St. Louis four points behind Nashville for the eighth and final spot in the West. Adding to the disappointment, the Blues could be without Tkachuk -- third on the team with 21 goals -- for an undetermined amount of time after he injured his wrist early in the third period.
"We've dealt with adversity all year and players in and out of the lineup," Murray said. "Obviously (Tkachuk) is a big part of our team and whenever you lose a guy like that it hurts. But we're used to it and continued to play hard."
That could make ending their losing streak to the Flames much more difficult.
St. Louis, which has been outscored 13-7 in three losses to the Flames this season, is 0-5-1 since winning 3-0 over Calgary on Nov. 25, 2007. The Blues haven't won at the Pengrowth Saddledome since Feb. 5, 2004.
Chris Mason made 18 saves in his 22nd start Thursday, and could be back in net trying to snap a three-game losing streak to Calgary. Mason is 18-20-6 with a 2.49 goals-against average in 2008-09, and 2-4-2 with a 3.61 GAA versus the Flames.
David Backes, who scored the Blues' most recent goal, has two in this last three games overall and two versus Calgary this season.
The Flames returned home from a 3-4-0 road trip and beat Dallas 2-1 on Wednesday. Light-scoring forwards Eric Nystrom and Jamie Lundmark each had a goal and Miikka Kiprusoff made 18 saves for his 200th victory.
Nystrom and Lundmark have combined for nine goals this season. Lundmark, though, has five and four assists in his last 11 games.
"We needed a game like that," Nystrom told the Flames' official Web site. "We've given far too many chances, far too many goals. The first line can't score every goal. We need the depth guys to step up."
All-Star and captain Jarome Iginla, who was held scoreless Wednesday after posting three points in an 8-6 loss at Toronto on Saturday, has three goals and three assists versus St. Louis this season.
With the win, Kiprusoff improved to 41-17-5 with a 2.85 GAA after having given up 19 goals in his previous four starts. He has dominated the Blues during his career, going 13-2-1 with a 2.29 GAA and 12 straight victories against them.
