Dermott replaced Rasmus Sandin in the lineup in Game 4 but the two will swap places again for Game 5. Dermott had two shots and two blocked shots in 12:57 TOI in his series debut.
Arvidsson has been out since April 27th but will play in Game 1 vs. Carolina. With Arvidsson back in the lineup, it looks like Eeli Tolvanen will sit out as a healthy scratch. Arvidsson has 10 goals and 15 assists (25 points) in 50 games.
