The Pittsburgh Penguins have activated defenseman Erik Karlsson from injured reserve, while placing Ryan Graves on injured reserve in a corresponding move. Karlsson, who has been out for nine days with an undisclosed injury, returns as the team’s highest-scoring defenseman, boasting 33 points in 44 games this season. His strong performance has improved the Penguins’ position regarding potential trades, while Graves, who has struggled for playtime, may be reassigned to the AHL upon activation.
