The Eagles will release guard Todd Herremans, likely by the end of Thursday, two NFL sources said.
Adam Caplan of ESPN was first with the report.
Herremans was the longest-tenured Eagles player along with linebacker Trent Cole. He was chosen in the fourth round of the 2005 draft and Cole was selected a round later.
The Eagles will save $2.8 million against their salary cap for 2015, but will lose $2.4 million in dead money with Herremans' release. They now have an opening at right guard. Allen Barbre would be the likely replacement as the roster stands.
The 31-year-old Barbre, who signed a two-year contract extension last May, missed most of last season with a broken ankle. The Eagles could also be inclined to fill the hole through free agency. The 49ers' Mike Iupati and the Raiders' Stefen Wisniewski could be options.
The Eagles could also look to the draft. They do need to get younger with left tackle Jason Peters (33) and left guard Evan Mathis (33) also over 30.
Herremans missed the last eight games of last season with a torn biceps. He managed to finish one game and started the first half of the next with the injury. Overall, he started 124 of 127 games played during his 10 seasons with the Eagles.
