There will be several other changes up front for the Bruins against the Sens as Jesper Froden - recalled from Providence on Wednesday - subs into the lineup as the second-line right wing. As such, Marc McLaughlin will shift down to be the fourth-line center, while Tomas Nosek will bump up to be the third-line left wing in place of Trent Frederic, who will be a healthy scratch.
"We talked to Freddy…it wasn't one incident," Cassidy said of Frederic's costly penalty against St. Louis on Tuesday night. "We talked in Tampa - his game was slipping a bit, his details. So, I'm trying to give him a chance to work out of it. That line in general, I think, their game isn't where it was a couple of weeks ago…it's not Freddy, to be honest with you.
"Coyle and Smitty have been around a long time. They're the guys that make that line go. Fred is a good complementary piece on there. So hopefully maybe just one player out it'll get them going a little bit.
"And hopefully get Freddy is right back in. He's been a good, good player for us. He's helped that line. That's the decision today."
McLaughlin, meanwhile, will get his first meaningful look at center - his natural position - at the NHL level after playing his first five games predominantly as a right wing.
"I'm definitely comfortable in that spot," said McLaughlin. "It's obviously great getting a chance to play with [Curtis] Lazar and [Nick] Foligno - two strong, defensively-minded players who play the game the right way and play hard. I'm sure they'll help me out a lot.
"There's definitely more responsibility playing the D-zone, especially. Just coming back hard and being in control and being in the right spots is what I'm trying to focus on tonight."
