The Penguins assigned defenseman P.O Joseph to Wilkes-Barre/Scranton of the American Hockey League.
With Mike Matheson hobbled by an undisclosed injury, Joseph was recalled to the NHL roster on Wednesday and was a healthy scratch for two games.
Joseph, 22, is considered one of the organization’s top prospects. In 16 NHL games last season, Joseph had five points (one goal, four assists).
He could make his season debut Sunday for the Wilkes-Barre/Scranton Penguins, who host the Charlotte Checkers.
Note: The Pittsburgh Penguins had a scheduled day off on Sunday.
