The Eagles signed safety and special-teams standout Chris Maragos to a three-year contract extension on Thursday, keeping Maragos under contract through 2019.

Maragos, 29, is in his seventh NFL season. He came to the Eagles in 2014 and has led the team in special-teams tackles since his arrival.

"From the first day he set foot in the city of Philadelphia, Chris Maragos has represented our organization at the highest level on and off the field," Eagles executive Howie Roseman said in a statement. "His work ethic, team-first attitude, accountability, and high character are things he brings to work every single day. And he happens to be one of the best special-teams players in the NFL, and we're excited to be able to extend his contract."

Maragos has played 80 percent of the special-teams snaps for the Eagles this season. He leads the team with eight special-teams tackles this season, and had a team-high 30 special-teams tackles in 2014 and 2015.

Tight end Zach Ertz missed practice Thursday with a hamstring injury. He told reporters he intends to play Sunday against the Seattle Seahawks. Safety Terrence Brooks was also out with an injured hamstring. Jordan Matthews was a limited participant with back spasms that kept him out Wednesday. Cornerback Nolan Carroll returned to practice after finishing the concussion protocol.
