Erik Karlsson says he looked down at his leg after he was cut and knew he had torn his Achilles right away. Karlsson said Friday that he plans to return at 100 percent. The normal recovery time for a lacerated Achilles is at least six months, but it can take longer for the player to regain his old form. Karlsson also said he hasn't returned a text message from Matt Cooke, whose skate was responsible for the injury. "He knows exactly what he's doing out there. And that's why I'm sitting here in a cast," Karlsson said Friday.
