PHILADELPHIA — The Eagles could be without their star tight end against the Miami Dolphins on Sunday, and a few other key offensive players still have their statuses up in the air.

Eagles coach Doug Pederson updated the injury statuses of tight end Zach Ertz, running back Jordan Howard, right tackle Lane Johnson and wide receivers Nelson Agholor and Alshon Jeffery on Friday at NovaCare Complex.

Here’s what he said about each player ...

TE Zach Ertz: The Pro Bowler has missed practice this week with a hamstring injury, though Pederson said it’s unclear when he suffered the injury. Ertz will run on grass at Friday’s practice and then the team will determine his readiness for Sunday. At best, the expectation should be that Ertz is questionable for Sunday’s game. If he’s expected to be out, the Eagles likely will start Dallas Goedert and sign Joshua Perkins off the practice squad to fill an open roster spot.

RB Jordan Howard: The running back has a shoulder injury suffered against the Chicago Bears in Week 9 and he’s yet to be cleared for contact. It’d be surprising if he played against the Dolphins.

RT Lane Johnson: The Pro Bowler has cleared concussion protocol and is expected to return to the starting lineup against the Dolphins.

WR Alshon Jeffery and WR Nelson Agholor: Jeffery (ankle) and Agholor (knee) both missed the Seahawks game last week despite Pederson saying earlier in the week that they were progressing toward a return. Both have been limited this week, and Pederson echoed a similar sentiment on Friday, saying “they’re both doing well. They’re trending in the right direction.”

Pederson insists there was no setback.

“No, because you gotta think they didn’t play in tye game so we’re trying to get them to this game, so we’re trying to limit them as much as we can, get them as much work as we can but at the same time be smart,” Pederson said. “This is the time of the year where you gotta be smart with some of your players with the amount of injuries that start piling up not only on our team but league wide. Those are two guys that have played a lot already and we just want to make sure they’re good to go for Sunday.”
