-- Forward Greg Rallo played just four shifts in his NHL debut, the 30-year-old arriving from Texas on Saturday.
Rallo said he was told of his NHL recall after Jack Skille was hurt Friday night allowing friends and family to book flights from Chicago and Alberta to be at Sunday's game. Rallo estimated a dozen made the trip.
“It's been a crazy couple of days. The family is really excited. This is a really big deal,'' he said before the game. “They spared no cost. They got here right away.''
