Ertz suffered the injuries when he took a hard hit from Cowboys safety Xavier Woods during the Eagles' opening possession of their Week 16 win over Dallas. He later returned to play through the pain, but won't be able to do so in a week in which the Eagles can secure the NFC East crown with a win.
Wide receiver Nelson Agholor (knee) was also ruled out.
Running back Jordan Howard (shoulder) has been cleared to return and is expected to play Sunday, coach Doug Pederson said Friday.
Howard hasn't played since the Eagles' Week 9 win over the Chicago Bears. His absence has left a void in the team's backfield, which has since turned to (and later waived) Jay Ajayi to fill the power back role. Philadelphia has recently run with rookie Miles Sanders and Boston Scott as the patchwork Eagles attempt to overcome a rash of injuries to make the playoffs.
Pederson added Howard will serve as the third-string running back Sunday, though it's difficult to imagine the Eagles not turning to him in short-yardage situations.
Tackle Lane Johnson (ankle) is questionable for Sunday's game, as is cornerback Jalen Mills (ankle).
Here is other news we're monitoring on Friday:
