PITTSBURGH (AP) ― Despite losing their captain, the Pittsburgh Penguins found a way to finish the month unbeaten.

Pittsburgh, gearing for a run at the Stanley Cup, welcomed star forward Jarome Iginla to the lineup, but lost Sidney Crosby early in the first period after he was hit in the mouth with a puck.

Still, the Penguins managed to overcome the injury to Crosby on Saturday for their 15th straight victory as Matt Cooke and James Neal scored third-period goals during a 2-0 victory against the New York Islanders.

“It’s very tough to see that happen to anybody on the ice, but this is your teammate and Sid’s such a great player,” Iginla said. “It’s a very, very unfortunate play.”

Tomas Vokoun made 35 saves as Pittsburgh moved within two wins of the NHL record of 17 straight victories set by Mario Lemieux and the 1992-93 Penguins.

“The shutout is nice, but preserving the winning streak is even better,” Vokoun said. “It’s been great.”

It might be tough without Crosby. Coach Dan Bylsma said Crosby lost several teeth and needed oral surgery. He did not know if Crosby would miss additional time and wasn’t sure if the injury affected his jaw.

“I just know he had some issues with his teeth,” Bylsma said. “Just from the replay I know that.”

Crosby, with 15 goals and 56 points, has enjoyed a resurgence this season, leading Tampa Bay’s Steven Stamkos by 10 points in the NHL scoring race.

Another head injury for Crosby, however, has to concern the Penguins.
