The Jets announced Wednesday that Perine has been placed on the reserve/COVID-19 list following his positive test, Ethan B. Greenberg of the team's official site reports.
According to Greenberg, the Jets are administering contact tracing for Perine to determine if any other players may have been affected. With the Jets already ruling out Frank Gore (lung contusion) for Sunday's season finale in New England and Perine now set to miss the contest, Ty Johnson and Josh Adams are the team's available backfield options, along with practice squad member Pete Guerriero.
