The Pittsburgh Penguins will be without defenseman Justin Schultz for the foreseeable future with a lower-body injury, head coach Mike Sullivan announced Thursday.

"He's a little more than week to week," Sullivan said. "I'm reluctant to put a time on it, but it'll be weeks."

The Penguins recalled Frank Corrado from the AHL to fill Schultz's spot in the lineup.

"The last time he was up, we really liked his game," Sullivan said of Corrado. "He's got a little bit of bite to him. He's a stiff player. He defends pretty well and he plays within himself. He's a calculated player out there - that's what we like about his game."

Corrado was acquired last season from Toronto and has failed to record a point in his five appearances with the Penguins. He did, however, score a goal and add four assists in 12 AHL games prior to the recall.

Through 23 games, Schultz - who missed time earlier this season with a concussion - contributed two goals and eight assists.
