Eagles HC Chip Kelly said tight end Zach Ertz will sit out the entire preseason with a nagging "core muscle" problem. He said Ertz should be ready for the season opener Sept. 14 at Atlanta. The Eagles later confirmed that Ertz had surgery, performed by Dr. William Meyers in Philadelphia. Center Jason Kelce said Ertz had a more minor tear than Kelce suffered last season, when Kelce was operated on by Meyers for a sports hernia and missed four games and five weeks. Kelce said it took a few weeks after he came back to really feel right again.
If Ertz had a 'more minor tear' than Kelce then it's possible he could heal more quickly than the five weeks it took Kelce to return to the field. If Ertz is out for four weeks, then he may be able to return to practice leading up to Week 1. For now, consider him questionable for Sep. 14, but be relatively confident that he returns by Week 2 or Week 3 at the latest.
