P.A. Parenteau scored in regulation and added the shootout winner in the Montreal Canadiens' 2-1 victory over the Buffalo Sabres on Wednesday night.

Dustin Tokarski made 31 saves to help Montreal end a three-game losing streak.

Parenteau opened the scoring 19 seconds into the third period with the Canadiens' first goal in 107 minutes, 1 second. In the third round of the shootout, Parenteau beat Michal Neuvirth with a wrist shot.

Drew Stafford tied it for Buffalo on a power play at 3:14 of the third scored, and Michal Neuvirth made 30 saves. Cody McCormick had a short-handed scoring opportunity in the slot midway through the third, but his backhander was kicked away by Tokarski.

The Sabres had a strong stretch in the Canadiens' zone with about 5 minutes to play that was foiled by Tokarski after Brian Gionta found Zemgus Girgensons with a no-look pass.

Montreal lost Michael Bournival for the night with an upper-body injury when Brian Flynn checked him hard in the corner. Bournival skated off the ice favoring his right shoulder.

The Sabres carried the play in the first period, finishing with a 9-5 shots advantage.

Montreal came to life in the second period, but Neuvirth made three early saves, the best a point-blank stop on Max Pacioretty.

Drew Stafford had a prime chance for the Sabres midway through the second, but Tokarski made the save. Moments later, the goalie made a sliding skate save on Chris Stewart.

Then came Parenteau, who slid a rebound past a prone Neuvirth to start the third period.

Buffalo got a power play, but lost a defenseman when Jiri Sekac boarded Nikita Zadorov at 2:23. Zadorov covered his face with a towel and immediately left for the locker room.

And the Sabres took advantage when Stafford took a pass from Tyler Myers and beat Tokarski to the short side for the Sabres' second power-play goal in 46 chances this season.

Tyler Ennis picked up the 100th assist of his career on the goal.

In overtime, Neuvirth made the biggest stop, sliding across to stop Pacioretty with 90 seconds to go.
