49ers' Armstead to miss most of offseason program with torn meniscus

San Francisco 49ers defensive lineman Arik Armstead will undergo surgery for a torn meniscus suffered in early December and miss most of the offseason program, the veteran said Tuesday, according to Michael Silver of the San Francisco Chronicle.

Armstead sat the final five games of the regular season after getting hurt in the Week 13 win over the Philadelphia Eagles. He returned for the postseason and played in all three of San Francisco's playoff games, including the Super Bowl loss to the Kansas City Chiefs.

The 30-year-old is coming off his ninth NFL season, all with the 49ers, who drafted him in the first round in 2015.

Armstead finished the 2023 regular season with 27 tackles and five sacks in 12 games before adding 11 tackles and one sack in the playoffs.

He's entering the final campaign of a five-year, $85-million contract.
