The Dolphins elevated Johnson from their practice squad Monday as a COVID-19 replacement.

EDGE Analysis

As Miami comes out of its Week 14 bye, Johnson currently is the only healthy back on the 53-man roster. The top three options on the depth chart -- Myles Gaskin, Phillip Lindsay and Salvon Ahmed -- were all placed on the reserve/COVID-19 list within the last few days following positive tests for the virus, while Patrick Laird (knee) joined Malcolm Brown (quadriceps) on injured reserve. Because all three of the backs that tested positive for COVID-19 are vaccinated, they'll all have a chance to be available for Sunday's game against Jets if they're asymptomatic for at least 48 hours and test negative on two occasions 24 hours apart. Meanwhile, Barry Jackson of the Miami Herald notes that Brown is expected to practice this week and could be available for Sunday's game against the Jets, so Johnson should have some competition for work even if none of Gaskin, Lindsay or Ahmed are cleared to play. Gerrid Doaks and Dexter Williams -- who have a combined seven carries for 19 yards between them in their careers -- linger as options on the practice squad that could be promoted if more depth is needed behind Johnson at running back.
