Mills rushed four times for nine yards while securing both of his targets for seven yards during Saturday's preseason loss to the Steelers.
With Jermar Jefferson seemingly locked into the No. 3 role behind D'Andre Swift (groin) and Jamaal Williams, Mills now seems to be in a battle with Craig Reynolds and Godwin Igwebuike for a potential No. 4 job at running back. While Mills didn't do anything special in this one, he did have an impressive 20-yard gain on fourth-and-1 in the preseason opener last week against Buffalo. If each of Swift, Williams and Jefferson are rested for the preseason finale, Mills could have his biggest exhibition workload yet when Detroit takes on Indianapolis on Friday.
