The Penguins on Wednesday sent Jason Zucker back to Pittsburgh so his lower-body injury could be further evaluated by doctors there.

The Penguins are holding out hope that the injury won’t be as bad as initially feared but are preparing to be without the top-six winger for an extended period.

“Zuck is a real resilient guy. He’s a good pro. He understands the game,” Mike Sullivan said after Wednesday’s practice. “And regardless of what kind of news we get, we know he’s going to work his tail off to get back as soon as he can.”

Zucker was injured on a fluky play in the third period of Tuesday’s 3-2 win over the Washington Capitals. He was skating to the point in the defensive zone when his skate collided with the skate of Capitals defenseman Nick Jensen. That knocked him off balance and he fell awkwardly in front of the Pittsburgh bench.
