Vatrano didn't practice ahead of Tuesday's clash with the Sharks while awaiting the birth of his child, Zach Cavanagh of The Sporting Tribune reports.
Vatrano hasn't found the back of the net in four games this season but did pick up helpers in each of his last two outings. If the 30-year-old winger isn't available against San Jose, the team may have to bring up a player from the minors unless Isac Lundestrom (upper body) is cleared to play.
