The San Francisco 49ers will release Arik Armstead after the two sides were unable to agree to a restructured contract.

Armstead is coming off a season in which he played in 12 games with 27 tackles and five sacks. 

Armstead was slated to count $28.53 million against the 2024 salary cap, which is why the Niners were seeking a reworked deal to reduce that number.

Armstead tore the meniscus in his right knee, an injury he suffered in a Dec. 3 win at the Philadelphia Eagles.
