Mattison (ankle) practiced fully Wednesday.
Top back Dalvin Cook (shoulder) also logged a full session Wednesday, which sets for Mattison to work as an understudy in Sunday's wild-card matchup with the Saints after both were sidelined for the final two games of the regular season. The rookie third-round pick played 15.4 snaps per game over his 13 appearances, finishing with 100 carries for 462 yards and a touchdown and 10 receptions for 82 yards on 12 targets.
