Mattison rushed 11 times for 34 yards and brought in three of four targets for 10 yards and a touchdown in the Vikings' 20-17 loss to the Buccaneers on Sunday.
Playing his first game as the Vikings' unquestioned lead back, Mattison came up considerably short statistically overall, even when factoring in his early fourth-quarter receiving touchdown. The fifth-year back was repeatedly stifled by a traditionally tough Buccaneers run defense, so perhaps the highly inefficient performance -- which featured a long run of just nine yards -- will prove to be an outlier over time. However, Mattison doesn't exactly get a reprieve in his Week 2 matchup, a road date with the Eagles on a short week Thursday night.
