Eric Decker has announced his retirement from the NFL.

Decker signed a one-year contract with the New England Patriots on Aug. 3.

On Saturday, coach Bill Belichick had been asked about Decker's acclimation to the Patriots' system and said, "I think Eric's learned everything well. Again, he had a background in this system in Denver with Josh [McDaniels] and he's played multiple positions in the offense since he's been here. We used a couple new formations [Friday], so I don't think learning is really a problem for him and he has a lot of experience of some of the more sophisticated routes, option routes and things like that are all things that he's done and it's just really a question of getting the timing and the exactly how you want to do it and seeing enough looks on it so that you and the quarterback know exactly what it is."

The Patriots had signed Decker after releasing Jordan Matthews.
