The Edmonton Oilers came from 4-2 down to beat the misfiring Colorado Avalanche 6-4 in a Northwest Division clash.

The rally began with 16 seconds remaining in the second period with a goal from Sam Gagner.

Ryan Potulny, Patrick O'Sullivan and Alex Hemsky then netted in the third period to ensure the Oilers snapped a four-game losing streak against the division leaders.

Michael Frolik scored twice as the Florida Panthers upset the Northeast Division-leading Buffalo Sabres 6-2.

Tomas Vokoun also starred for the improving Panthers with 26 saves.

He was bettered by Alex Auld, though, who made 31 saves for the Dallas Stars as they beat Detroit Red Wings 3-1.

Mike Ribeiro, Matt Niskanen and Loui Eriksson got the goals for Dallas, while Henrik Zetterberg was on target for the Red Wings.

Scotty Upshall got the winning goal for the Phoenix Coyotes in a 3-2 win over the Minnesota Wild.

It came just 19 seconds after Antti Miettinen had levelled for the Wild in the third period.

In the day's other game, the Philadelphia Flyers beat the Los Angeles Kings 3-2.
