It seemed unlikely just a couple of weeks ago, but the Eagles believe they will have an extension hammered out with Patrick Robinson before legal tampering begins on Monday, according to Ian Rapoport of NFL.com (on Twitter). Robinson emerged as both a key defensive player and a locker room leader for Philadelphia in 2017. 
The Eagles don’t have a ton of cap room to work with, even after trading wide receiver Torrey Smith. The acquisition of Michael Bennett from the Seahawks has also set them back a bit, though that move will allow them to trade or release Vinny Curry before the majority of his $9MM salary becomes guaranteed for the coming year.
If Robinson isn’t retained by Philadelphia, the rival Giants will be among the teams with interest in signing him in free agency.
Not sure how they’re going to fit him into already tight salary cap.
