Chris Phillips could be missing from the Ottawa Senators lineup Tuesday against the Philadelphia Flyers. The veteran defenceman and Senators assistant captain is nursing a minor injury and coach Paul MacLean said Tuesday morning that it will be a “game time” decision on whether he suits up against the Flyers, his favourite team when he was a child growing up in Northern Alberta. If Phillips is out, Joe Corvo will be brought back into the lineup. The defensive pairings at Tuesday’s morning skate were Jared Cowen-Erik Karlsson, Marc Methot-Mark Borowiecki and Patrick Wiercioch-Corvo. The forward lines remained the same from Monday’s practice, with the high scoring trio of Clarke MacArthur, Kyle Turris and Bobby Ryan staying together. Other lines included Milan Michalek-Jason Spezza-Cory Conacher, Colin Greening-Zack Smith-Chris Neil and Matt Kassian-Derek Grant-Mika Zibanejad. Spezza’s wingers have been in constant flux, so don’t be surprised if MacLean tinkers. One possibility is that Zibanejad could move up to play with Spezza. Many eyes will also be on Craig Anderson, who returns to the Senators net for the first time since suffering a neck injury against the Dallas Stars on Nov. 3. In his absence, Robin Lehner went 3-0-0, with a 1.33 goals against average, backstopping the Senators to their current three-game winning streak.
