"I think we're pretty familiar with Harry and what he brings to the table - lots of speed and lots of energy," coach Peter Laviolette said before the Flyers lugged their 1-6 road record into Tuesday's game. "He's been here before, so I think he's comfortable."
A former Ivy League player of the year at Brown, Zolnierczyk was recalled because Sean Couturier is sidelined with the flu. Couturier, who returned to Philadelphia, has missed the last two games.
"It's huge. You've got to take advantage of those opportunities, and I've got one here now and plan to take advantage of it," said Zolnierczyk, who became the first Flyer to wear No. 12 since Simon Gagne. "I know what I have to bring to help this team."
Zolnierczyk, 25, said he didn't get discouraged, even when some Phantoms teammates were promoted before him.
"I could only control what I could do and make sure I was playing my best down there and be ready for my chance," he said.
Zolnieczyk began Tuesday on a line with Max Talbot and Zac Rinaldo.
New captain Claude Giroux entered Tuesday with just seven points - and had failed to produce a point in eight of 13 games.
"He's probably frustrated," Laviolette said. "We've said from the start he wants to make a difference, he wants to see this team be successful, and I think he feels frustration when that's not happening. But I think it's a matter of time with Claude and the points will come."
A year ago, Giroux, who centered Matt Read and Wayne Simmonds on Tuesday, finished with 93 points, third in the league.
To make room for Zolnierczyk, the Flyers placed Jody Shelley on injured reserve, saying he had a hip injury. . . . Entering Tuesday, the Flyers were second in the NHL with 344 hits and third with 199 blocks. . . . The Flyers began the night leading the league in a dubious category - minor penalties, with 75.
