"I suspect those guys will go back in Saturday and we'll look at some other players for that game depending on how tonight goes," said Cassidy, who will be coaching in his 300th career game.
Marcus Johansson took part in an optional pregame skate on Thursday morning and is expected to play. The winger has been dealing with the "residual effects" of a collision with Krejci during Tuesday's win in Columbus.
"I think he'll be ready to go," said Cassidy. "If not, March would have to go in or we play seven D. But I think he's gonna play."
Danton Heinen, who sat out against the Blue Jackets because of an illness will be back in the lineup.
Even with a number of key pieces taking the night off, Cassidy expects a competitive effort from his group, especially with a handful of young players sliding into the lineup, including former first-round pick Zach Senyshyn, who will be making his NHL debut.

"I expect us to play well," said Cassidy. "We still have things we need to clean up. We play to win every night. I still think we've got a lot of good players, a lot of hungry players, motivated players.
"Obviously [Senyshyn and Trent Frederic] are trying to get their foot in the door. Danton Heinen is back in. I assume he'll have some jump. Charlie [Coyle's returning to Minnesota]. Johansson's building chemistry there. Jaro [Halak] back in the net. [Connor] Clifton-[Steven] Kampfer had to sit a few games, so I think there's plenty to play for.
"As a team, we want to get to win No. 49, right? Once the puck drops, one of the best things about our team is they're a very competitive group no matter what the situation is. I don't see us not having the juice."
