Marsh logged four tackles (two solo), including one sack, and a forced fumble in the Steelers' 16-3 preseason win over the Cowboys in Thursday's Hall of Fame Game.
Marsh stripped quarterback Garrett Gilbert in the red zone early in the second quarter Thursday, but the Steelers were unable to recover the ball. However, the 2014 fourth-rounder made an impact as he attempts to carve out defensive snaps ahead of the regular season.
