That injury sent him to the hospital, Rapoport's sources said.
The #Eagles won’t have TE Zach Ertz today, but he has not been ruled out for next week if Philly advances. Ertz is not only dealing with a cracked rib, but sources say he suffered a lacerated kidney that had him in the hospital after the game. That explains the caution this week.— Ian Rapoport (@RapSheet) December 29, 2019
Ertz was injured when he took a hit from safety Xavier Woods in the first quarter against the Dallas Cowboys last week.
Ertz left for the locker room a short time later, but he returned to finish the game and ended with four catches for 28 yards.
Ertz did not practice all week.
There was no word on whether Ertz would be available for the playoffs after the Eagles clinched the NFC East after beating the New York Giants on Sunday.
