Predators coach Barry Trotz doesn’t sound as if he’ll be wasting any time getting new faces into the lineup. Two forwards picked up on waivers this week, Bobby Butler and Zach Boychuk, as well as newly recalled defenseman Victor Bartley, are likely to be in the lineup against Edmonton on Friday at Bridgestone Arena. The Predators (9-9-5) have lost three games in a row. “I don’t want to limit myself, but obviously it hasn’t been working in a lot of areas for us,” Trotz said. “So there’s a good chance we’ll probably put all three of them in.” Boychuk, a former first-round pick by Carolina, skated Wednesday in practice on a line with center Mike Fisher and wing Patric Hornqvist. Butler, who has 39 points in 108 NHL games, skated with center Craig Smith and wing Martin Erat. Butler was also part of the first-team power-play unit, along with Fisher, Colin Wilson, Shea Weber and Sergei Kostitsyn. “Bobby Butler is more of a shooter. He gets to the harder places and has had success,” Trotz said. “Zach Boychuk … his No. 1 thing is he’s got good speed and a good skill-set. But he hasn’t produced yet at the NHL level. This is an opportunity hopefully for him to do that.”
