General manager Bryan Murray reiterated Friday that he isn't certain when Anderson (hand) might be ready to return from injured reserve, Wayne Scanlan of the Ottawa Citizen reports.Anderson has already missed about a month due to a deep contusion on his hand, far longer than the team initially anticipated. While a bruise isn't an overly serious injury, it's provided complications for Anderson in maneuvering a stick with his blocker hand. He's been able to practice off and on for the last couple of weeks, but until he notices more healing with the injured hand, the Senators don't want to risk using him in games. With Anderson and Robin Lehner (concussion) both out indefinitely, Andrew Hammond has since assumed the No. 1 goalie gig for the Senators.
