Miami Dolphins running back Phillip Lindsay is joining his backfield mates on the reserve/COVID-19 list, NFL Network's Tom Pelissero reported Monday.
Lindsay tested positive for COVID-19, Pelissero added.
The Dolphins previously placed Myles Gaskin and Salvon Ahmed on the reserve/COVID-19 list late last week after positive tests. With Lindsay joining them, Miami currently doesn't have any running backs on the active roster. The trio's status for Sunday's game against the New York Jets is in doubt.
Dolphins safety Jevon Holland is also going on the reserve/COVID-19 list.
Miami had a bye in Week 14.
Lindsay, Gaskin and Ahmed are all vaccinated, which means they have a chance to "test out" of protocols with two negatives before Sunday, Pelissero reported.
Veteran Duke Johnson has been elevated to the active roster, NFL Network's Cameron Wolfe reported. The team also worked out veteran free-agent Lamar Miller on Monday, but is not signing him at this time, Wolfe reported.
Since being claimed by the Dolphins after his release from Houston, Lindsay appeared in one game for the Dolphins, earning 12 carries for 42 yards. He missed Week 13 due to an ankle injury.
