Doug Pederson confirmed a flurry of reported lineup changes on Saturday, including the decision to move Jason Peters to right guard. The latter move was forced by Lane Johnson’s season-ending surgery.

“I’m excited for J.P. He’s excited,” the head coach said on Saturday. “A great opportunity for him. Listen, he’s obviously a tremendous player, tremendous Eagle and moving back to right guard.”

Like a giant Jenga game, the whole Eagles’ offensive had to be reconfigured as a result. Pederson credited the team’s “next man up” mentality in announcing that Matt Pryor would be the starting right tackle moving forward and ditto for Jordan Mailata at left tackle. This marks the 10th different offensive line iteration in 11 games.

“Mailata, he’s played well. He’s been consistent. Played good the other day,” Pederson said. “So, he gets another opportunity. Really not an opportunity, but a start at left tackle.”

Meanwhile, the Eagles officially ruled Pro Bowl tight end Zach Ertz out for Monday night. He had been “trending in the right direction” all week but needs a little more time to get comfortable. Ertz was activated to the 21-day practice window on Nov. 16 after suffering a high-ankle sprain on Oct. 18.
