PHILADELPHIA (973espn.com) - The big guy was back at Eagles practice Wednesday, albeit in a limited fashion.

Left tackle Jason Peters worked in individual drills for the first time since going down with a back injury against Carolina before the bye week. The veteran All-Pro, who confirmed he had a pinched nerve, was unable to get in any preparation before Philadelphia's win in Dallas on Sunday but was listed as questionable for the game before being downgraded to out on Saturday.

In his absence the Eagles moved starting right tackle Lane Johnson to the left side and inserted Dennis Kelly at right tackle. The move was designed to keep the interior intact and also put Kelly, a lengthy player who is a natural tackle, in the best position to succeed.

“I think (Johnson) did well,” Peters said. “He played good. I was talking to him, helping him every play. And we got the win, man. That’s all that matters.”

The makeshift lineup held its own and then some against the Cowboys but Peters' presence is a necessity for long-term success on the offensive line.

“Right now it’s like 50-50,” Peters claimed. “I’m not sure right now. It just depends on what the coaches decide. If I had to make a decision today, I’d tell coach I’d play but it’s going to be up to him and how I feel.”

In other injury news, star safety and slot corner Malcolm Jenkins missed his second straight practice after suffering a concussion against Dallas. Eagles coach Chip Kelly, however, said he's not worried about Jenkins and expects him back on the practice field by Thursday.

With Jenkins sitting out, Chris Maragos got the first-team reps next to Walter Thurmond.

Meanwhile, rookie wide receiver Nelson Agholor practiced again Wednesday in an attempt to return from the ankle injury that has caused him to miss three games.

"Nelson is good," Kelly said. "Again it’s how does he progress through the whole week of training. He did good yesterday and he’ll go back out today, but he’s somebody we have to monitor in terms of where he’ll be. He was good early last week, and then I think being out on the field kind of wore him down a little bit. He was good yesterday and said he felt good today, but we’ll see how that goes."

Backup safety Jerome Couplin missed the session with a shoulder problem, while linebacker DeMeco Ryans (hamstring), receiver Riley Cooper (toe) and offensive lineman Josh Andrews (head) were all listed as limited.

“We’ll continue to see how the week goes, but I’m confident and very optimistic that I’ll be out there on Sunday (against Miami),” Ryans said.
