Forward Jason Spezza is doubtful after not playing in a 3-2 shootout loss at the Chicago Blackhawks on Thursday because of back spasms. Coach Lindy Ruff typically juggles his defense pairings after a loss, so defenseman Stephen Johns could return to the lineup after being scratched the past two games. Goaltender Kari Lehtonen has started the past four games, but after making 24 saves Thursday, Antti Niemi could get his first start since March 14. Forward Ales Hemsky scored two goals Thursday and has five points (three goals, two assists) in 10 games since returning from a hip injury that had kept him out since Oct. 22. "I thought he put together a nice game for us," Ruff said Thursday. "He's skating well. Every game for me he seems to be getting better. And it's a lot of time off. We've seen it with other players. It's hard to come back and get in a groove right away."
