Mattison had three carries for five yards in Sunday's win at Denver.
Minnesota never got its running game going and fell behind early, both factors that limited Mattison's involvement. Mattison continues to have an impressive rookie season (4.8 yards per carry) but isn't getting enough touches for viable fantasy value in most formats. He's a backup worth rostering, though, as he could have significant value as a starter should Dalvin Cook get hurt. He also has a good chance of seeing a solid amount of carries in any game where Minnesota has a secure second-half lead.
