SEATTLE -- The Seahawks released defensive linemen Quinton Jefferson and Shelby Harris on Tuesday, the team announced.
The moves save Seattle approximately $13.4 million in cap space and come one day after the Seahawks and former Denver Broncos defensive lineman Dre'Mont Jones agreed to a three-year deal reportedly worth $51 million.
Jefferson, who turns 30 on March 31, played in all 17 games last season and made three starts. His 5.5 sacks and six tackles for loss were both career highs.
Jefferson returned to Seattle last offseason on a two-year, $9.
