PITTSBURGH (AP) — James Neal scored twice and Sidney Crosby had a goal and two assists to help the Pittsburgh Penguins beat Ottawa 4-2.

The Senators lost star defenseman Erik Karlsson to a left Achilles injury that will require surgery. 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.

In other NHL action:

— Alexander Steen stuffed in a rebound 52 seconds into overtime, lifting the St. Louis Blues to a 4-3 win over the Detroit Red Wings. St. Louis snapped a five-game losing streak that followed a 6-1 start.

— Mike Cammalleri had three goals and an assist in his return from a hip injury to help the Calgary Flames beat the Dallas Stars 7-4. The goals were Cammalleri's first of the season and give him 200 for his career.
