With the NFL regular season winding to its end, the Philadelphia Eagles are down to their third-string quarterback.

Starter Jalen Hurts remained in concussion protocol and did not start in Sunday’s game against the Dallas Cowboys. Then, in the third quarter, backup Kenny Pickett left the game after taking a shot to the ribs.

The injury took place on a pass play in the red zone. Pickett threw the ball in the end zone, and took a shot from Micah Parsons that left him doubled over in pain.

Pickett’s touchdown pass to Devonta Smith was overturned by a holding penalty, and third-string quarterback Tanner McKee took over for a third-down handoff before the Eagles kicked a field goal.

The Eagles listed Pickett as questionable to return with a rib injury. McKee remained in the game for another series as Pickett went to the locker room for evaluation of his injury.

Philadelphia, which has already clinched a playoff berth, held a 24-7 lead over the Cowboys at the time of Pickett’s injury.
