Washington scored three times in a 6:21 span early in the second to erase a 2-0 deficit. The Capitals, who also had two goals disallowed, had been held to 11 goals during their 0-6-2 skid.

Ryan Shannon and Chris Kelly scored in the first for Ottawa.

Perreault, who was sick and didn’t play Saturday night in a 3-2 loss in Boston, gave Washington its first lead on a power play 6:55 into the second for his second goal of the middle period.

He scored his first goal of the game 34 seconds into the second to draw the Capitals to 2-1. Fehr, who assisted on Perreault’s second goal, tied it at 2 with his fifth goal at 1:20 after having another waved off when time expired at the end of the first.

Michal Neuvirth stopped 24 shots for Washington, which also had an apparent goal by Alex Ovechkin disallowed later in the second. Brian Elliott made 31 saves for Ottawa.

Ovechkin got his team-leading 26th assist and 38th point on Fehr’s goal. The Capitals’ captain saw his goal drought extended to six games, though, when a video review wiped out his tally 9:14 into the second which would have put Washington up by two.

Stars 4, Red Wings 3 — Loui Eriksson scored at 4:18 of overtime to give Dallas a comeback victory in Detroit.

Eriksson also had two assists, Brenden Morrow scored twice, Brad Richards added a goal, and Andrew Raycroft stopped 28 shots to help Dallas pull within a point of conference-leading Detroit.

Chris Osgood made 28 saves in an unsuccessful bid for his 400th career victory.

Blackhawks 3, Kings 2 — Jonathan Toews, Duncan Keith, and Fernando Pisani scored, and rookie Corey Crawford made 26 saves for host Chicago.

The Stanley Cup champion Blackhawks won their second straight game, allowing only one power play after a penalty-free game Friday in a 4-1 victory over Detroit.

Avalanche 3, Canadiens 2 — Kevin Porter and T.J. Galiardi scored in the second period and Craig Anderson made 27 saves for host Colorado, as Montreal lost for the fourth time in five games.
