BUFFALO, N.Y. (AP) -Marian Hossa scored twice and Chris Osgood tied Dominik Hasek for 10th on the NHL career wins list in helping the Detroit Red Wings to a 4-1 victory over Buffalo on Monday night.
Hossa, who reached the 40-goal plateau for the third time, added an assist. Brad Stuart and Nicklas Lidstrom also scored for the Central Division-leading Red Wings, who are four points behind league-leading San Jose.
The Sabres' playoff chances grew slimmer as Buffalo lost its second straight. With three games left, Buffalo is 10th in the Eastern Conference, four points behind the New York Rangers and Florida at the postseason cutoff.
Osgood made 32 saves, picking a fitting game to earn his 389th victory and tie Hasek, the former Red Wings starter who spent most of his career with Buffalo. He lost a bid for his 50th NHL shutout with 10:06 left, when Paul Gaustad made it 3-1.
MONTREAL (AP) - Dany Heatley scored two goals 38 seconds apart to put Ottawa ahead with 7:59 remaining in the third period, and the Senators dealt a big blow to Montreal's playoff chances.
Heatley lifted Ottawa into a 2-2 tie at 11:23 and then netted his 37th of the season at 12:01 when he beat Jaroslav Halak on a shot from the slot that silenced the sold-out Bell Centre crowd.
Chris Campoli also scored for the Senators, who will miss the playoffs for the first time in 13 seasons.
Alex Kovalev netted his 25th goal, and Roman Hamrlik scored with under 4 seconds remaining in the second period for the Canadiens, who are seventh in the Eastern Conference but only three points above the playoff cutoff with three games left.
Halak stopped 20 shots in his third straight start for Montreal, which lost top defensemen Andrei Markov and Mathieu Schneider to injuries in Saturday's 6-2 in Toronto.
CALGARY, Alberta (AP) - Jarome Iginla had a goal and an assist to lead Calgary to a pivotal victory over Los Angeles.

The Flames outshot Los Angeles 19-5 in the second period and grabbed a 2-1 lead. Daymond Langkow, David Moss and Jim Vandermeer, with his first goal in 75 games, also scored for Calgary.
Wayne Simmonds netted the lone goal for Los Angeles.
