The Jaguars are slated to sign Armstead (knee), Aaron Wilson of KPRC 2 Houston reports.
Armstead, whose deal is reportedly for three years and $51 million, per Adam Schefter of ESPN, immediately becomes a linchpin of Jacksonville's defensive front, fixing a huge need for the team along the interior of the defensive line. The 30-year-old is recovering from surgery undergone to address a torn meniscus, which he played through during the 49ers' postseason run.
