The Penguins assigned center Oskar Sundqvist to Wilkes-Barre/Scranton of the American Hockey League.
He was recalled Friday as a precaution after center Nick Bonino suffered an undisclosed injury during practice.
Sundqvist, 22, has played in 12 NHL games this season and has one assist. In 44 AHL games, he has 44 points (five goals, 12 assists).
