The Jaguars placed 12 of their 16 practice squad players on the reserve/COVID-19 list, Tom Pelissero of NFL Media reports.
Defensive end Josh Mauro, who is suspended, also is going on the reserve/COVID-19 list.
The Jaguars had one practice squad player return a positive test Friday night. The other players were placed on the list after contact tracing determined a proximity issue, according to Pelissero.
Jacksonville’s practice-squad players sit in a separate area during meetings in case one tests positive. No players on the active roster were exposed, so the Jaguars still plan to play Sunday’s game against the Lions.
