The Cowboys' official site called Nall a fullback when announcing the signing, so that is likely where Dallas plans to use him if he makes the roster. Regardless of his position designation on offense, special teams will be where Nall makes a push for the roster. 

Hicks was already ruled out with an ankle injury. Nall, the Bears' last-string running back, carried the ball one time for four yards and caught a four-yard pass across 19 snaps this season.

Nall was called up from the practice squad mid-2020 to form a committee with Artavis Pierce and Cordarrelle Patterson — the extent of the former's career highlights — for David Montgomery. With 13 career touches and vast special teams experience as a blocker, Nall still has a tremendous chance to land on a practice squad ahead of Week 1.

An exclusive rights free agent, Nall's choices were accept the Bears' offer or retire. A 2018 UDFA, Nall is a special teamer with 13 career touches, 11 of which came in 2020. He turned 25 in December.
