Chicago Bears quarterback Justin Fields was listed as inactive for Sunday's game against the host New York Jets in East Rutherford, N.J.
The Bears (3-8) named Nathan Peterman as their starting quarterback versus the Jets (6-4) after Trevor Siemian -- who was expected to get the nod -- sustained an oblique injury during pre-game warmups.
ESPN reported that running back David Montgomery will serve as the emergency backup for Chicago.
Fields is nursing an injury to his non-throwing (left) shoulder sustained in last Sunday's 27-24 loss to the Atlanta Falcons.
Fields has passed for 1,642 yards, 13 touchdowns and eight interceptions in 11 games this season.
