The Eagles placed second-year linebacker on Injured Reserve following Friday's practice opening a spot on the 53-man active roster ahead of Sunday's regular-season finale against the Dallas Cowboys.
Walker originally suffered the injury in the second quarter of the November 26 rout of the Chicago Bears. He missed the two games on the West Coast before returning to action in the Week 15 win over the Giants and playing six snaps on special teams. He was inactive for Monday night's game against Oakland and did not practice on Friday.
A seventh-round pick of the Eagles in 2016 out of Oregon, Walker rebounded from a season-ending ACL injury as a rookie to make 10 tackles and a pass deflection in 12 games (three starts) this season. He played 99 total snaps on defense and also had three stops on special teams.
