Sissons received a match penalty late in Game 5 for cross-checking Pittsburgh Penguins defenseman Olli Maatta in the face.
Preds head coach Peter Laviolette told reporters he didn't believe Sissons intentionally checked Maatta high:
"I watched it play out. I saw Maatta cross-check him, Colton cross-checked him back, Maatta cross-checked him again, and they were doing it somewhere in the midsection. On the last one, Maatta seemed to slip and his head dropped. I don't think there was any intention there whatsoever, so—I don't think so, but that's not my call."
Sissons has been a key part of Nashville's deep and varied offensive attack in these playoffs with six goals and six assists for 12 points in 21 games.
During the regular season, the 23-year-old had just eight goals and two assists for 10 points in 58 contests.
Nashville fell 6-0 in Game 5 and will enter Sunday's Game 6 trailing in the series 3-2.
