Hansen (knee) was designated to return from the Saints' injured reserve Wednesday, Nick Underhill of NewOrleans.Football reports.
Hansen will now have a 21-day window to return to practice before he needs to be activated to the 53-man roster. Otherwise, he'll revert to IR for the remainder of the season. Hansen logged four tackles as a core special-teamer over the first eight games of the season, and his next chance to play will come Sunday versus Atlanta.
