Eagles extend Trent Cole's deal

The Philadelphia Eagles spent the 2011 free-agency period adding players. This year, the team is taking a different approach -- rewarding players already on the team.

Defensive end Trent Cole became the second Eagles player to get an extension in two days, agreeing to a four-year deal, the team announced Wednesday. The extension puts Cole under contract through the 2017 season.

A source told ESPN NFL Insider Adam Schefter that Cole's extension is worth $48.525 million in salary, including $15 million guaranteed. The deal could be worth $55.25 million if escalators in the contract are triggered.

While the Eagles decided to extend Cole, they cut ties with center Jamaal Jackson on Wednesday, a team official told Schefter.

On Tuesday, Philadelphia agreed to a three-year extension with offensive lineman Todd Herremans.

"We are excited to be able to sign Trent to a new contract," coach Andy Reid said in a statement. "Trent plays the game with a level of tenacity that's hard to replicate. He's one of the premier defensive ends in the league. We have always said that when you watch the tape of him, it's hard to tell the difference between his first play and his last play.

"He has an unbelievable motor that does not stop. And as good as he is rushing the passer, he is equally as good against the run. His energy is contagious on the field."

The two-time Pro Bowler's 68 career sacks have him third all-time on the team's list behind Reggie White (124) and Clyde Simmons (76).

Cole had 11 sacks in 2011, his third straight season with double-digit sacks.
