Left tackle Jason Peters signed a four-year extension Wednesday, ensuring he won't hit the free agent market in 2015.  Now coming off a breakout season that saw him grade out as Pro Football Focus's top center - Jason Kelce will be here long-term.

The Eagles have re-signed their starting center, to a six-year, $37.5 million contract extension, the deal includes $13 million guaranteed, according to agent Jason Bernstein of XAM Sports.

Kelce had one year at $645,000 remaining on his rookie deal, so this is really a seven-year deal that takes the 26-year-old through 2020.

“Jason is the epitome of the type of player we want around here, both on and off the field," Eagles head coach Chip Kelly said about Kelce.  "He’s tough, extremely intelligent and is a leader by his actions and by his words. His athleticism is something that really sticks out when you watch him play. There aren’t many centers that can get down the field like he does.”

Kelce, a sixth-round pick, won a starting job as a rookie and has started every game for which he has been available.  This deal puts Kelce's within the top-5 centers in the NFL on an average per year basis.

“You just don’t see many interior linemen with the athleticism that Jason Kelce possesses," Eagles GM Howie Roseman described.  "It shows up on film many times where you just see him 10 or 15 yards down the field making blocks. His intelligence, work ethic and pride in his game are just off the charts. He’s the proverbial gym rat and is always at the NovaCare Complex working on his game. This was the first off-season we had to re-sign Jason and we jumped all over the opportunity.”

After singing Jason Peters yesterday, the Eagles now have their entire talented starting offensive line locked up through at least 2016, which is fantastic news for LeSean McCoy and Nick Foles.

With Kelce leading an offensive line that saw the same five players start every contest, the Eagles offense flourished as he helped the team set franchise records in points scored (442) and total net yards (6,676). Kelce also assisted in paving the way for the NFL’s leading rusher in LeSean McCoy, who finished with franchise bests in both rushing yards (1,607) and yards from scrimmage (2,146).
