Jake Allen is the expected starter for the Blues.
Calle Jarnkrok sealed it with an empty-net marker at 19:00, making him Nashville's 14th different goal-scorer of the playoffs. Johansen had been held off the scoresheet in each of Nashville's previous four games, but he picked a great time to break out of his slump.
Steen finished third on the team in scoring during the regular season with 51 points (16 goals, 35 assists) in 76 games. Goaltender Pekka Rinne has been in net for every game and is off to an 8-2 start in the 2017 playoffs.
Facing elimination on Sunday afternoon the St. Louis Blues will be getting some help when one of their top players, veteran forward Alex Steen, returns to the lineup.
Nashville bested the Blues in six games, 4 games to 2, in front of a home crowd at Bridgestone Arena in Nashville. The Predators scratched D Anthony Bitetto, RW PA Parenteau, RW Miikka Salomaki, D Brad Hunt, C Frederick Gaudreau, G Marek Mazanec, LW Pontus Aberg and LW Harry Zolnierczyk.
