Mattison will welcome back Dalvin Cook (shoulder) to the Vikings backfield for Thursday's game against the Steelers.

EDGE Analysis

Mattison is coming off his third spot start of the season for Cook in which he took 25 touches for 124 yards from scrimmage and one rushing TD during this past Sunday's loss at Detroit. With Cook back in the lineup and wearing a harness on his previously dislocated left shoulder, there's a chance Mattison spells Cook at times to ease the pressure on Minnesota's top running back. Still, when Cook has been available this season, Mattison has averaged just five touches per game.
