Erik Karlsson is done for the season. Brenden Dillon now plays for the Washington Capitals. Jacob Middleton went down with what looked to be a gruesome lower-body injury in the Sharks' win over the Pittsburgh Penguins on Saturday, and fellow rookie defenseman Mario Ferraro was ruled out of both of San Jose's games this weekend with the same injury description.
Yeah, it would be fair to say the Sharks' defensive corps has taken a beating over the last month.
San Jose's depth in the back end has been tested due to the quick succession of departures from the lineup.
