PITTSBURGH, Pa. - James Neal scored twice and Sidney Crosby had a goal and two assists to help the Pittsburgh Penguins beat Ottawa 4-2 on Wednesday night in a game marred by the loss of Senators star defenceman Erik Karlsson to a left Achilles injury.

The Norris Trophy winner last season as the NHL's top defenceman, Karlsson was cut by Penguins forward Matt Cooke's skate blade as the two tangled along the boards late in the second period. The Senators said Karlsson will need surgery.

Pascal Dupuis also scored for Pittsburgh, Paul Martin had two assists, and Marc-Andre Fleury made 26 saves. The Penguins snapped a two-game losing streak to pull within a point of Eastern Conference-leading New Jersey.

Stephane Da Costa scored his first goal of the season, and Jim O'Brien also scored for Ottawa. The Senators lost for the fifth time in seven games.

St. Louis goalie Jake Allen, making his first NHL start in his second game in the league, made 15 saves. Jaroslav Halak missed his fifth straight game because of a groin strain.
