Ludvig was placed on waivers by the Penguins on Friday, Elliotte Friedman of Sportsnet reports.
Ludvig featured in 33 NHL games for Pittsburgh last year and seemed to have a decent chance of making the Opening Night roster. Instead, the Czech blueliner will be headed for AHL Wilkes-Barre/Scranton, assuming he goes unclaimed. Still, even with the demotion, Ludvig should be atop the team's list of potential call-ups should the need arise.
