The San Francisco 49ers have agreed to sign Arik Armstead to a five-year deal worth up to $85 million.

The 49ers decided to sign Armstead long-term on the same day they traded DeForest Buckner to the Indianapolis Colts.

Armstead had a breakthrough season in 2019, leading to his new contract. Armstead had 10 sacks in 2019.

“Arik’s physical tools and versatility have allowed him to be highly productive in our style of defense, and we look forward to watching him take his game to an even higher level as he grows within our scheme,” general manager John Lynch said. “Arik has been an impact player on the field and a difference-maker in our community, and we are excited for what the future holds for him.”
