The Vikings are expected to place Jefferson (hamstring) on injured reserve this week, Tom Pelissero of NFL Network reports.
Jefferson will be forced to miss a minimum of four contests if he's indeed placed on IR as a result of the right hamstring strain he sustained in Sunday's loss to the Chiefs. Peliserro relays, however, that the star wideout's exact recovery timetable has yet to be determined, meaning he could be sidelined for longer than four weeks. An extended absence from Jefferson would leave Jordan Addison and K.J. Osborn as the Vikings' top receivers, with tight end T.J. Hockenson potentially becoming Kirk Cousins' go-to target. Next on deck for Minnesota is a matchup against the Bears on Sunday.
