Philadelphia Eagles tight Zach Ertz had groin surgery. He's out for the rest of the preseason. Ertz is expected to return for the start of the regular season. "The biggest thing for us in this situation, to be honest with you, is that it's something that we wanted to get cleaned up," Eagles coach Chip Kelly said. "So the reps weren't really important. I think in the long term he's going to be a lot better for it. We just wanted to get it out of the way."
