For all intents and purposes, Mattison was serving as the Vikings RB1 once again since Cam Akers saw his season come to an end with an Achilles injury. That treatment continued against the Saints on Sunday, but he wasn’t able to salvage his fantasy day before suffered his concussion. In his relief, RB Ty Chandler saw increased run in the ground game and added a touchdown to cap off a serviceable day in Minnesota’s backfield. Concussions tend to be one-week injuries, so fantasy managers can expect Mattison to be back in short order – but in the meantime, Chandler is the ball carrier to pick up off the waiver wire. Chandler will likely offer flex appeal in a solid matchup against the Broncos in Week 11, while Kene Nwangwu should remain on waivers for the time being.
