Norris Trophy winner Erik Karlsson hurt in Ottawa’s loss

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 Pittsburgh in a game marred by the loss of Senators star defenseman Erik Karlsson to a left Achilles’ injury.

The Norris Trophy winner last season as the NHL’s top defenseman, 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 27 saves.
