The Ottawa Senators have never won a series when down 2-0 so they consider Friday night's Game 2 a must-win.

There willl be two lineup changes for Ottawa as Andre Benoit steps in for the injured Eric Gryba on defence and Guillaume Latendresse is in, likely for Matt Kassian.

Discipline will be key for Ottawa after they were dominated by the Pittsburgh Penguins in Game 1 in special teams. Pittsburgh was officially 2-4 on the power-play, while Ottawa failed to score.

The Penguins are looking to prevent a letdown like they had in the first round where they defeated the New York Islanders 5-0 in Game 1 before falling 4-3 two nights later.

Game 2 is at 7:30 p.m. ET on Hockey Night in Canada (CBC, CBCSports.ca) from the Consol Energy Center in Pittsburgh, Pa.

Dan Séguin has more on CBC TV News starting at 5 p.m. ET in Ottawa, while Stu Mills has reports throughout the day and tomorrow morning on CBC Radio One, 91.5 FM in Ottawa.
