Brian Boucher, taking over No. 1 goalie duties from injured Ray Emery, made 22 saves for the Flyers, who broke a five-game losing streak. Philadelphia has won 12 in a row and 15 of 16 against the Islanders, dating to the 2007-08 season.

The Flyers had dropped two consecutive games - including an 8-2 home loss to Washington Saturday - after Laviolette replaced John Stevens Friday.

Rookie John Tavares scored both goals for New York, which dropped its second straight and slipped into a last-place tie with the Flyers in the Atlantic Division.

Richards’s first goal came on a power play, and snapped a five-game, 0-for-19 stretch with the man advantage for the Flyers. Richards deflected Kimmo Timonen’s slap shot past goalie Martin Biron.

Just 6 minutes later, Richards scored the first shorthanded goal allowed by the Islanders this season.

The Flyers (14-13-1) were 12-5, but their slump led to Stevens’s dismissal.

Canadiens 4, Senators 1 - Jaroslav Halak made 45 saves, and Tomas Plekanec had three assists as Montreal extended its winning streak to three with a road victory over Ottawa.

Mike Cammalleri, Marc-Andre Bergeron, and Andrei Kostitsyn all scored for the second night in a row, and Scott Gomez added an empty-net goal.

Canadiens right winger Ryan White played four shifts in the first before he was removed from the game because he was ineligible. Montreal recalled White from Hamilton of the AHL earlier in the day but neglected to inform the NHL.

Predators 4, Canucks 2 - Martin Erat had his second career hat trick and added an assist to lead Nashville over visiting Vancouver. The Predators beat the Canucks at home for the first time since Nov. 23, 2006.

After winning the first two games of a four-game trip, the Canucks lost at Carolina and Nashville.

Patric Hornqvist had the other goal for the Predators. Ryan Kesler and Daniel Sedin scored for Vancouver.

Ducks 4, Stars 3 - Dan Sexton, playing in his third NHL game, scored his first two goals - the second with 62 seconds left in regulation - and Saku Koivu scored 4:13 into overtime to give Anaheim a home victory over Dallas.

Joffrey Lupul also scored, Bobby Ryan had two assists, and Jean-Sebastien Giguere made 19 saves, helping the Ducks snap a five-game losing streak that included an overtime loss and two more defeats in shootouts.
