Jason Jones, who visited St. Louis and then Seattle, agreed to terms with the Seahawks, the team announced Saturday.
Seattle envisions Jones, formerly of Tennessee, providing depth behind Red Bryant at the five-technique spot while also providing pass-rush help from the inside. For Jones, the opportunity provides a chance to redefine himself as a defensive tackle after appearing out of position at defensive end last season.
Jones, 25, has 15.5 sacks in four NFL seasons. He is 6-foot-5, 276 pounds and has 28 starts over the past two seasons.
