Vaki (ankle) did not participate in practice Thursday.
Vaki missed practice for the second straight day due to an ankle injury that occurred in the Lions' Week 9 win over the Dolphins. The 25-year-old will likely need to practice in some capacity Friday for a chance to play in Week 10 against the Patriots in Germany. If Vaki is unavailable Sunday, Jacob Saylors will likely serve as the No. 2 back behind Jahmyr Gibbs against New England.
