Dumoulin had multiple tendons in his ankle lacerated in Saturday's loss to St. Louis and is expected to miss at least two months after undergoing surgery on Sunday morning. Injuries have been a huge issue for the Penguins this season but they've managed to stay afloat and will likely take the Dumoulin injury in-stride as well. He logged big minutes on their blueline, so someone like Marcus Pettersson is likely going to be tasked with taking on a larger role moving forward.
