Lagesson was placed on waivers by the Red Wings on Sunday, Elliotte Friedman of Sportsnet reports.
Lagesson signed a one-year contract with the Red Wings on Monday but will be let go ahead of the regular season. He made a career-high 40 regular-season appearances between Toronto and Anaheim last year, tallying four points and 58 blocked shots while averaging 14:48 of ice time. If he clears waivers, he'll likely begin the season in the AHL.
