What happened: Devin White shifted to the second unit Wednesday, while Keith Abney II handled every nickel snap with both the first- and second-team defenses. Jahmyr Gibbs turned two bottled-up outside-zone carries into gains of 9 and 8 yards, and Aidan Hutchinson beat Blake Miller for a sack on the next play after one of those runs.

Why it matters: Ben Bartch worked at left guard with the second and third units, while Tay Martin and Ben Stille continued competing near the roster bubble. Detroit's one-hour session in shells gave each offense only three drives, increasing the weight of the remaining evaluations.

What to watch: Thursday's practice will show whether Rodriguez keeps the first-team role. Detroit closes the preseason Saturday before Sunday's 6 p.m. cut to 53 players.
