Kosmachuk, 22, has 14 goals and 13 assists in 59 games with Manitoba. Winnipeg selected him in the third round (No. 70) of the 2012 NHL Draft. Kosmachuk's Manitoba teammate, Josh Morrissey, played his first NHL game Saturday.
"Just energy," Kosmachuk said when asked what he planned to add to the lineup. "The Jets are in need of some help here, and I'm hoping to bring that."
Nashville has a franchise-record 12-game point streak (8-0-4) as a five-game road trip continues and had an optional morning skate.
Defenseman Barret Jackman will be a healthy scratch for the fourth straight game. Laviolette said Jackman still serves as an example to his younger teammates.
"He works hard every day," Laviolette said. "There are always different routes that you can go down. He always does the right thing. He's a terrific leader in our [dressing] room, a terrific player, a terrific person."
Pekka Rinne will make his sixth start in a row for the Predators. Maurice will start Ondrej Pavelec for the third consecutive game.
With center Paul Gaustad (upper body) out, Nashville recalled Colton Sissons from Milwaukee of the AHL on Monday to replace him. Coach Peter Laviolette will not make any other lineup changes. Sissons, 22, has a goal and an assist in 19 games for Nashville.
"I probably bring that more defensive game, faceoffs and penalty kill up here [than in Milwaukee]," Sissons said of what his role will be with Nashville.
The Jets conclude a five-game homestand having lost seven of their past eight games at home. They have three wins in 15 home games in 2016.
Kosmachuk is the seventh Winnipeg player to make his NHL debut this season.
"You only get one [debut]," Jets coach Paul Maurice said of his message to Kosmachuk and others playing their first NHL game. "It's a big game for them in their lives, for their family, their peewee coaches, for anybody who has ever come across the player in small-town Canada. [A debut] is a huge night for all of [those people]."
