Karlsson hasn't played since sustaining a 70-percent tear of the Achilles' tendon in his left leg when he was stepped on by the Pittsburgh Penguins' Matt Cooke during a game Feb. 13.
The 2012 Norris Trophy winner underwent surgery to repair the cut Feb. 14, and was expected to miss 3-4 months. He had 10 points in 14 games at the time of the injury, and was averaging 27:03 of ice time per game.
I don't think today was my most solid game that I've had, some rebounds here and there. I know there's a lot of work to do, not every game is going to go as good as these last few. I've just got to make sure I keep working and keep trying to get better.
