Scarlett has been cut from the Dolphins' practice squad, Barry Jackson of the Miami Herald reports.
Following the move, Miami's 53-man roster includes fellow running backs Myles Gaskin, Malcolm Brown and Salvon Ahmed. Scarlett, a 2019 fifth-rounder, logged four carries for nine yards in nine games during his rookie season with Carolina, but didn't suit up for any NFL regular-season action in 2020.
