New Orleans Saints left tackle Terron Armstead has reached an agreement on a five-year extension that will tie him with the team through 2021.
Armstead was entering the final year of his rookie four-year deal.
He has started 27 games the last two seasons, including 13 in 2015.
The 24-year-old lineman is a tremendous athlete who has emerged as one of the league's top young tackles in recent years.
