Impact Karlsson logged 23:12 of ice time in Sunday's clash with the Bruins, so it's not immediately clear when he suffered this undisclosed injury. With his placement on IR, the Swedish blueliner will be out of action for at least the next three games, though it could certainly be longer. In order to bolster the team's defensive options, Ryan Graves was called up from the minors in a corresponding move.
