Recommendation: Though a timetable for Karlsson's recovery isn't available at the moment, it looks like the 22-year-old will be on the shelf for an extended period of time, possibly the rest of the season. Karlsson, who is leading the Senators with six goals this year, suffered the laceration just before the end of the second period of Monday's game, when the skate of Matt Cooke caught Karlsson after a collision along the boards. Look for Ottawa to IR Karlsson and add a defenseman from the AHL.
Update: Karlsson will need surgery after suffering a laceration to his left Achilles during Monday's game against the Penguins. He will be out indefinitely.
