Allen recorded 10 tackles (three solo) and a pass breakup in Sunday's 27-23 loss to the Cowboys.
With Akeem Davis-Gaither (knee) out versus Dallas, Allen played all 79 defensive snaps for Indy, marking the first time the second-round rookie has played 100 percent of the defensive snaps in a game. He's started back-to-back contests and is up to 25 tackles (nine solo), including 1.0 sacks, and the one pass breakup across six appearances this season.
