OTTAWA (AP) -- Pascal Dupuis scored 9:56 into overtime for the Pittsburgh Penguins, who erased a three-goal deficit and eliminated the Ottawa Senators from the playoffs with a 4-3 victory in Game 6 on Saturday night.
The Senators led 3-0 in the second period and appeared to go up 4-1 in the frame, but lost a goal to video replay when it was determined the puck crossed the line after the net was knocked off its moorings.
Matt Cooke scored his second of the game with 7:36 left in regulation to tie it at 3. Bill Guerin had a goal earlier in the third.
Matt Cullen and Daniel Alfredsson each had a goal and an assist for Ottawa, which won Game 5 at Pittsburgh in triple overtime to stave off elimination. Pascal Leclaire made 38 saves, and Chris Neil also scored for the Senators.
Marc-Andre Fleury stopped 28 shots as the Penguins won for the eighth time in nine playoff series after they were eliminated by Ottawa in five games in the first round in 2007.
CHICAGO (AP) -- Patrick Kane's short-handed goal tied the game with 13.6 seconds left in regulation and Marian Hossa came out of the penalty box to score 4:07 into overtime as Chicago beat Nashville to take a 3-2 lead in the first-round series.
Chicago can advance in the Western Conference playoffs with a win at Nashville on Monday night.
The Blackhawks blew a 3-1 lead, and the Predators went ahead 4-3 with two third-period goals by Martin Erat.
With Nashville protecting its lead late and on a major power play created by Hossa's boarding penalty against defenseman Dan Hamhuis, Kane tied it with his third goal of the series.
The Blackhawks killed the remaining 3:57 of Hossa's penalty in overtime. The Predators are the only team in this year's playoffs without a power-play goal. Their latest failure with the game on the line pushed the drought to 0 for 21 with the advantage.
Andrew Ladd, Niklas Hjalmarsson and Tomas Kopecky also had goals for Chicago in regulation.
David Legwand had a goal, and Joel Ward added a short-handed tally for the Predators.
