Vatrano (personal) was activated from the non-roster list Saturday.
Vatrano missed Friday's 4-3 overtime loss to Colorado to attend the birth of his child. He will likely occupy a middle-six role and see time on the second power-play combination versus the Kings on Sunday. Vatrano has one assist, five shots on goal, three blocked shots and four hits in three appearances this season. His return will probably bump Ross Johnston from the lineup.
