Eagles TE Zach Ertz took a nasty fall at the end of a third-down play at the beginning of the second quarter.
Ertz hit the ground hard, with his neck snapping back, after he attempted to hurdle a defender.
Ertz was taken back into the locker room by the doctors to be examined for a head injury. He was diagnosed with a concussion and didn't return.
Ertz was recovering from a core body injury in preseason and was slowly getting back to 100-percent, putting together some solid fantasy outing over the past few weeks. Brent Celek has stood out in the Eagles offense the past few weeks, too, and could end up being a sneaky TE play if Ertz can't get back on the field.
