Craig Anderson doesn't know when he will be able to return from his finger injury. "It's hard to say ... obviously the timeline is wide open right now," Anderson said. "All I can do right now is make sure I stay in shape. I'm able to go out there and skate with my gear on. The main thing right now is keeping my legs, keeping everything strong, so when I do have a chance to come back, I'm physically ready to go." The Ottawa goaltender required surgery to repair a severed tendon to his pinky and he's still not able to grip his stick. Robin Lehner is expected to make his third consecutive start on Friday night against Chicago in Anderson's absence.
