Vikings head coach Kevin O'Connell said Wednesday that he doesn't believe Jefferson's hamstring injury to be a season-ending one, Alec Lewis of The Athletic reports.
O'Connell didn't divulge the grade of Jefferson's right hamstring strain, but the injury is severe enough for him to miss at least the team's next four games while on injured reserve. While Jefferson is sidelined, Minnesota's passing attack may become more balanced between tight end T.J. Hockenson, wideouts K.J. Osborn and Jordan Addison and running back Alexander Mattison. However, Addison was a limited participant at Wednesday's practice due to an ankle injury, potentially removing another key pass catcher from the mix if he's unable to overcome the issue ahead of Sunday's game in Chicago.
