SEATTLE -- The Seattle Seahawks plan to release defensive lineman Quinton Jefferson, a source told ESPN's Adam Schefter.
The move saves Seattle around $4.5 million in cap space and comes 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.
