The Philadelphia Eagles have announced that they have released two defensive tackles from their contracts with the team.
General manager Howie Roseman said in a statement: "I had a chance to speak with Cullen today and let him know of our decision. It's one of the most difficult parts of the job.
"He has been a very productive player in this league for a long time, but we felt it in our team's best interests that we go in a different direction."
Patterson added: "The Eagles' organisation has treated me and my family with nothing but respect since the day I was drafted and I wish Mr Lurie, Howie, the new coaches and all of my teammates all the best going forward. I will miss them all and I will always have a place in my heart for the Eagles and for the city of Philadelphia."
Patterson made six tackles and one sack during the 2012 campaign, while Jenkins recorded 26 tackles, four sacks and a forced fumble.
