The Seahawks added to their interior defensive line on Tuesday, claiming defensive tackle Isaiah Mack, who was waived by the Ravens on Monday.
Defensive tackle Daviyon Nixon, who signed with the Seahawks last week and was inactive for Saturday's game against Kansas City, was waived to make room on the 53-man roster.
Mack, who went undrafted out of the University of Tennessee at Chattanooga, made the Titans roster as a rookie and appeared in 13 games with one start. Since then he has spent time with New England, Denver, Pittsburgh and Baltimore, appearing in four games for the Ravens over the past two seasons.
Mack gives the Seahawks interior line depth with Bryan Mone going on injured reserve last week, and with Al Woods' status still uncertain due to the Achilles injury that has kept him out of the past two games.
Additionally, rookie receiver Bo Melton was signed off of Seattle's practice squad to Green Bay's 53-man roster. Melton, a seventh-round pick out of Rutgers, has spent the entire season on the practice squad.
