The San Francisco 49ers have signed three defensive linemen over the past week, and they are not wasting time getting them into the mix. The 49ers signed Leger Douzable and Tony McDaniel last week, and added Datone Jones this week. The moves came following a season-ending injury to Arik Armstead, and an injury to Aaron Lynch that will leave him out an undetermined amount of time.
Douzable replaced Armstead as a starting defensive end last week, while McDaniel worked into the defensive tackle mix.
