The Lions elevated Small from the practice squad to the active roster Saturday ahead of Sunday's matchup versus the Dolphins.
Small signed with the team's practice squad in September and is now set to be elevated for the first time this season. With Sione Vaki (ankle) and Jacob Saylors (neck) both dealing with injuries, Small could be in line to serve as Detroit's No. 2 running back behind Jahmyr Gibbs against Miami.
