Mims reverted to the Titans' practice squad Monday, per the NFL's official transaction log.
Mims was elevated to the active roster prior to Sunday's 26-0 loss to the Texans, failing to log any snaps in the contest. The running back could earn another elevation in Week 5 if Tyjae Spears (ankle) isn't ready to return from injured reserve before the team's matchup with the Cardinals.
