The Seahawks signed defensive end Malliciah Goodman on Tuesday.
Goodman played in 34 games over three seasons with the Falcons, starting 11. The Falcons released him in September when they trimmed their roster to the regular-season size of 53.
A fourth-round pick in 2013, he has two career forced fumbles and two fumble recoveries.
The Seahawks placed defensive tackle Quinton Jefferson on injured reserve. He was injured in practice last week. Also Tuesday, the Seahawks worked out free agent defensive end Wallace Gilberry.
