Eagles tight end Zach Ertz will be forced to sit out Monday's game against the Bears with a rib displacement suffered in Week 1, coach Doug Pederson said Saturday.

This wasn't a surprise as Ertz was trending that way since the news broke about his rib. He's officially week-to-week according to the team but there's no timetable for his return outside of that. Trey Burton and Brent Celek will take over. Burton is a guy the team is high on and someone to keep an eye on in this contest.

Sunday’s opener went well for the Eagles overall, but tight end Zach Ertz did emerge with an injury that could keep him out of the lineup for a little while.

Eagles coach Doug Pederson said at a Monday press conference that Ertz suffered a displaced rib under his collarbone during the victory over the Browns. Pederson described Ertz as “week-to-week” and said that his return to the lineup will be up to when he’s cleared by doctors rather than his ability to tolerate any pain resulting from the injury.

Ertz had six catches for 58 yards on Sunday. Brent Celek was the only other tight end active with Trey Burton inactive with a calf injury, so the Eagles may need to bring in someone else at the position. If Burton can get on the field for Week 2, he could be a sneaky pickup at the position as the team is on record as liking his offensive skills.

After Jordan Matthews went down in practice a couple of weeks ago with a knee injury and Zach Ertz had to be tested for a concussion, the tight end expressed his frustration about how the Eagles’ rookies were hitting during practice.

But Matthews said today, in his first media availability since his injury, he’s not upset with Jalen Mills’ low hit and he'll be ready Week 1.

“I’m not the type to get mad. Getting upset or anything isn’t going to help my knee get any better,” Matthews said. “Right after it happened, Jalen came up to me and was like, ‘Yo bro, I’m so sorry. I didn’t realize.’ I just looked at him and was like, ‘It’s cool, bro. I’m fine.’ I’m just not the type to get pissed off about that. It’s football."

It’s unclear when Matthews will return and if he’ll play in the preseason, but he said he’ll “for sure” be good to go for the regular season. The 24-year-old, who played through a painful hand injury last season, added that the Eagles’ two preseason games are the only games he’s missed in his entire life since he began playing sports.

The Eagles’ running backs and wide receivers won’t be near any lists for the top groups in the NFL, but their offensive hopes go beyond those skill positions. Look for the tight ends to fill a major role in the offense, with Zach Ertz, Brent Celek, and Trey Burton all a part of the passing game.

“Tight end is a strength of this roster, this offensive unit,” offensive coordinator Frank Reich said. “If you look at Doug’s [Pederson] system and what they did in Kansas City with their tight ends and how we’ll utilize them here, it’ll be very consistent with that, and we’ve got the players to do it. We can mix it up. They’re all real good, smart route runners – every one of them. So, we expect really good production from that unit.”

Ertz will be the biggest contributor of the group. Ertz caught 75 passes last season for 854 yards and two touchdowns. The receiving yards and touchdowns could see a jump this season. There were five tight ends who led their teams in receiving yards last season. Ertz might join that group that season. Jordan Matthews, Nelson Agholor, and Darren Sproles will all be big parts of the passing offense, but the best mismatch could come from Ertz.

We had a story Sunday on the Eagles looking to involve Trey Burton in the offense, someone who has been a relative unknown with only two years in the league and three career catches. Expect him to split out wide and/or come out of the backfield. Celek is more than a capable receiver, but the safe fantasy bet seems to be Ertz here, and the story talked a lot about his skills.

Jordan Matthews suffered a left knee sprain, but Doug Pederson told SiriusXM that Matthews will just be sore for a few days.

Zach Ertz, who was also evaluated for a head injury, was cleared, but he was clearly unhappy with how some of his teammates have approached the hitting periods. Ertz was hit low by Blake Countess today and by Rodney McLeod two days ago.

“Guys gotta be pros,” Ertz told reporters after practice. “Rookies coming in, they don’t know what the atmosphere is like, the respect that’s given in practice.”

Seems like both players will be fine, which is good news. The original report of the injury said both hits were low and borderline dirty.
