The 16-year veteran is expected to play right guard after spending virtually his entire career as a tackle, according to Ian Rapoport of NFL Network. ESPN's Adam Schefter noted he will replace the injured Brandon Brooks, who will miss all of 2020 because of a torn Achilles.
Andre Dillard, the team's 2019 first-round pick, should remain the starting left tackle. He played well when Peters missed three games last year with a knee injury.
Peters has put together a Hall of Fame resume since going undrafted in 2004.
The Texas native was an unheralded draft prospect because of his limited work as an offensive lineman at the University of Arkansas. He spent time as a reserve defensive tackle and tight end before starting the transition during his final year with the Razorbacks.
It took another season of development with the Buffalo Bills—Peters played just five games as a rookie—before he broke through. He appeared in all 16 games the following year, including 10 starts, and from there he transformed into an elite asset at the crucial left tackle position.
After five years in Buffalo, the Bills traded Peters to the Eagles for a first-round pick and a fourth-rounder shortly before the 2009 NFL draft.
Peters' career accolades include nine Pro Bowl appearances, six All-Pro selections (two first-team and four second-team) and a Super Bowl title with the Eagles in 2017.
Now 38, the 6'4", 328-pounder said following the 2019 season he planned to keep playing and hoped to remain with the Eagles.
"I told 'em I wanted to play another year. I still can get it done," Peters told reporters in January. "If I couldn't get it done, I'd just walk away, but I can still go. I want to be here ... but the nature of this business, sometimes they move on. We'll have to see."

Nine-time Pro-Bowl OT Jason Peters, who turned 38 in January, has been working out to play this season and plans to play this season. He has spoken with the Eagles, but is keeping his options open: This is a video that Peters recently shot that he wants teams to see. https://t.co/YnrWzZ44FD
Peters remained a valuable asset last season, receiving a strong 82.4 overall grade from Pro Football Focus.
Slotting the veteran presence between proven options Lane Johnson at right tackle and Jason Kelce at center should once again make this offensive line one of the best in the NFL.
