According to Field Yates, the Eagles have restructured Lane Johnson's contract to save $7.5 million on their cap.
Celek, 33, is one of the best tight ends in Eagles history.
Celek is now known as the longest tenured athlete in Philadelphia.
The 33-year-old has appeared in all but one game with the team over his 11 National Football League seasons.
Danny Amendola expected to sign with Miami Dolphins
However, he did his best work during the playoffs, where he caught 33 balls for 348 yards with two touchdowns in three games. As for the Patriots, they should still be fine at wide receiver for next season even with Amendola's absence.
Celek finished with 398 catches for 4,998 receiving yards and 31 receiving touchdowns in his 175 games with the Eagles.
The Eagles diminished Celek's role in the offense over the past two seasons.
Don't be surprised if a few other Eagles' players help the team move money around - like Jason Peters - so the team can add a few more Ngata-like players as they look to build on last year's depth and injury-versatility.
Robinson was one of four former Florida State stars to get a Super Bowl ring this season - joined by defensive tackle Timmy Jernigan, linebacker Nigel Bradham and fellow defensive back Ronald Darby, all of who have signed long term deals with the team.
Numerous players who battled alongside Celek in 2017 to win Super Bowl LII shared glowing thoughts about their now former teammate. In 2009, Celek recorded career highs in receptions (76), receiving yards (971) and receiving touchdowns (eight). But when looking at how much he's been through since coming on board in 2007, both good and bad, Celek deserves all of the credit in the world for sticking it out with Philadelphia, as he's always been one of the most respected players in the locker room.
