As head coach Todd McLellan told the media (relayed by The Athletic) ahead of the game against the Preds, he is dealing with a lower-body injury and is considered day-to-day.
Kevin Fiala suffered the injury in a game against the Colorado Avalanche when he had a knee-on-knee collision with Andrew Cogliano in the second period. He tried to play again in the third period but had to throw in the towel after one shift.
