Armstead Placed on IR

Tuesday, Nov. 8

Doug Kyed of NESN reported Armstead's move to the IR list. Matt Barrows of the Sacramento Bee previously noted the injury has plagued the lineman since he first suffered it Aug. 10 during training camp.

The 49ers later announced the roster move and confirmed they claimed defensive tackle Chris Jones off waivers from the Miami Dolphins to fill the void.

Armstead Has Failed to Make Significant Contribution at NFL Level

Armstead wasn't terribly impactful as a rookie, but he was healthy. Appearing in all 16 games, the University of Oregon product accumulated two sacks and 19 total tackles as a rotational rusher thanks to his massive 6'7", 296-pound frame. 

"At some point in his career, man, he's going to be a dominant force, and he's going to be terrorizing everything, even in the locker room," former 49ers defensive tackle Darnell Dockett said, according to ESPN.com's Paul Gutierrez. 

In eight games this season, Armstead posted 2.5 sacks and 15 total tackles working off the edge for new head coach Chip Kelly. 

Armstead is a powerful presence who can pack a punch alongside defensive staples Ahmad Brooks, Aaron Lynch and fellow Oregon product DeForest Buckner, so losing him has set the team's front seven back a bit. 

With Armstead now out, Buckner could continue to see his snap count balloon as he attempts to hold down the fort on the left side of San Francisco's defensive line. Quinton Dial and Ronald Blair are also in for more playing time up front.
