Cullen (undisclosed) isn't on the ice for pregame warmups and appears in line to miss Tuesday's tilt with the Canadiens. With both Cullen and Viktor Stalberg not skating due to undisclosed injuries, emergency call-up Kevin Fiala will join the lineup to fill out the Preds' forward ranks. Cullen was able to skate Tuesday morning before being ruled out, so there's still a chance he could be ready to go for Thursday's tilt with the Lightning.
