Miller has a workout scheduled with the Dolphins on Monday, Barry Jackson of the Miami Herald reports.
The Dolphins could be without their top three running backs, as Myles Gaskin and Salvon Ahmed are both on the reserve/COVID-19 list while Phillip Lindsay is battling an ankle injury. If signed, Miller -- who played in 61 games for Miami from 2012 through 2015 -- could take on a prominent role in Week 15 against the Jets if none of the three aforementioned running backs are cleared to return by then.
