Lavoie was picked up off waivers by Vegas from Edmonton on Monday, Elliotte Friedman of Sportsnet reports.
Lavoie has just seven games of NHL experience, all of which came last season. In those outings, the 24-year-old center notched four shots, 13 hits and two PIM while failing to get onto the scoresheet. Even with the move to Vegas, Lavoie is far from a lock for the lineup on a nightly basis and will have to compete with the likes of Keegan Kolesar and Victor Olofsson for minutes.
