Nashville Predators defenseman Ryan Ellis won't play because of a lower-body injury. He left during the second period of a 2-1 loss at the Montreal Canadiens on Thursday and did not return. Matt Irwin filled his spot alongside Roman Josi at the morning skate Saturday. "He's played great," captain Mike Fisher said of Irwin. "He's been solid all year. He's played some really quality minutes, and whenever he's been out there he's been solid and steady for us and done a really good job. I can't say enough about him as a teammate. The way he's played, it's been fun to see." Anthony Bitetto is expected to replace Ellis in the lineup. The Predators are third in the Central Division and could play the Blackhawks in the Western Conference First Round of the Stanley Cup Playoffs. "There's a chance, no question [of seeing the Blackhawks in the playoffs]," Fisher said. "All of these games, we know, are so important. Against Chicago, they're always heated battles and great games. We're playing against a really good hockey team, and they're going to force us to be at our best."
