The Philadelphia Eagles officially announced that tight end Zach Ertz underwent successful surgery to repair a core muscle injury.
As noted earlier on Friday, Eagles head coach Chip Kelly said Ertz is expected to miss the entire preseason. Kelly did say that Ertz should be back in time for Philadelphia's week one game against the Atlanta Falcons, however. That game is set to take place exactly one month from day on Monday, Sept. 14.
Ertz recently met with sports hernia specialist Dr. Williams Meyers recently. According to a report from Jeff McLane, however, Ertz did not suffer a sports hernia. Instead, he suffered a partial groin tear.
For perspective, Eagles center Jason Kelce missed four games last season with a sports hernia injury. His injury was more serious than Ertz's is believed to be, however.
With Ertz out, it's up to second year tight end Trey Burton and the Eagles' undrafted rookie free agent tight ends to take advantage of additional playing time in the preseason.
