The Vikings activated Mason (thumb) from injured reserve Saturday, and he does not carry an injury designation into Sunday's game against the Colts.
Mason has spent the four-game minimum on IR while recovering from a thumb injury, and the veteran running back has been given the green light to return for Week 7. He'll rejoin Aaron Jones in the backfield for Sunday's game, and the veteran duo figure to operate in a timeshare as they did last season.
