Vaki (ankle) is listed as questionable for Sunday's game against the Dolphins.
Vaki appeared on Friday's injury report as a non-participant with a new ankle injury. The backup running back had 70 total yards in the Lions' Week 8 win over the Vikings. If Vaki must miss Sunday's contest, Jacob Saylors (neck) or a practice squad elevation will likely play the reserve role behind Jahmyr Gibbs.
