Erik Karlsson is struggling to regain his form after returning to action from a sliced Achilles tendon. He has not looked good against the Penguins and was particulalry vulnerable on Pittsburgh's first goal Friday night as Sidney Crosby blew by him and beat Craig Anderson. As a result, Sens' coach Paul MacLean cut Karlsson's ice time for the remainder of the contest. If you are relying on Karlsson in a playoff pool, we suggest you look for alternatives until the Sens' rearguard shows he is in better game shape.
