Mattison could have a big opportunity Sunday, as the Vikings are pessimistic about Dalvin Cook (questionable - ankle) suiting up for their game against the Seahawks, Ian Rapoport of NFL Network reports.

EDGE Analysis

Cook is a game-day decision and could have a limited role even if he's active. Last year, Mattison had one dud (Week 6) and one huge performance (Week 17) in his two fill-in starts, and he should handle a large workload Sunday if Cook doesn't end up playing. Ameer Abdullah is the only other tailback on Minnesota's roster for Sunday's game, with the team opting not to call up preseason star A.J. Rose from the practice squad.
