The Penguins played most of the game with four defensemen after Brian Dumoulin and Kris Letang each left because of injury at 16:23 of the first period. Dumoulin has a concussion from a hit by Wayne Simmonds, and Letang was being evaluated for an upper-body injury.
"Those are a tough two guys to replace," Schultz said. "They're two of the more important guys on this team. To lose them early like that wasn't easy. I thought the guys did a good job and played simple. It's unfortunate we couldn't get the win."
Elliott made 30 saves through the second period, including 18 in the first. It was his first start since Nov. 15 because of a lower-body injury, although he played the previous two games in relief.
"It was big in the standings, for sure, against a big rival," he said. "We had a lot of fans in the stands. They braved it, the weather, just as we did out there. It was really fun to play that. ... I definitely didn't want to let the guys down, and they didn't let me down, they came back for me."
The Penguins have lost seven of their past 11 games.
"You've got to move by it, and we've got to learn from it," Crosby said. "I mean, this is kind of a playoff feel, I think, from here on in for us, and sometimes things like this happen."
