Rhodes (knee) is listed as questionable for Sunday's tilt with Carolina, Ben Goessling of ESPN reports.
With Trae Waynes' sloppy play as of late, the Vikings are anxiously awaiting Rhodes' return to action. The hope is that he'll be available for the big game, but if not, Minnesota is prepared for Waynes and the ageless-wonder Terrence Newman to anchor the secondary Sunday.
Henicke will start the regular season on the non-football injury list, Andrew Krammer of the Star Tribune reports.
Heinicke was originally given a timetable of three months for a return when he had surgery to repair a torn tendon in his ankle. Placement on the NFI list to start the season means that he'll miss at least the first six games, which he likely would've anyway.
