The Ottawa Senators learned Saturday night that they would be facing the Pittsburgh Penguins in the Eastern Conference Semifinals, leading some to wonder how the Senators will handle another round of drama after their emotional series with the Montreal Canadiens.

The Senators have a postseason history with the Penguins -- they haven't beaten Pittsburgh in the playoffs since 2007, where they were victorious in the first round en route to an appearance in the Stanley Cup Final, and eventual loss to the Anaheim Ducks. Since that time, the Senators have lost twice to the Penguins, in 2008 and 2010, both series taking place in the quarterfinals.

The incident this season involving Penguins wing Matt Cooke and Senators defenseman Erik Karlsson did nothing to warm relations between the two clubs. Cooke's skate sliced through the left Achilles tendon of Karlsson during a game on Feb. 13, and the Swede required surgery to repair the cut.

Much was made of the incident at the time, but Karlsson is ready to move forward and refuses to let history become a distraction.
