The Vikings signed Dallas from the practice squad to the active roster Wednesday.
With Jordan Mason (thumb) landing on injured reserve, Dallas will presumably jump into a prominent role behind Aaron Jones. The 2020 No. 144 overall pick has appeared in contests for the Seahawks, Cardinals, Panthers, Jaguars and Vikings during his career. In 84 regular-season games, Dallas accumulated 538 yards and four touchdowns off 124 carries, adding 64 catches for 407 yards and two touchdowns.
