McGinn (back) was placed on waivers Thursday, Elliotte Friedman of Sportsnet reports.
By waiving McGinn, the club can move him down to the minors and activate him off non-roster injured reserve. The winger will likely spend some time in the minors getting his legs back under him, but he could earn a promotion sooner rather than later. If he does crack the Panthers' lineup, it figures to be in a bottom-six depth role.
