The Seahawks added an accomplished veteran to their defense on Wednesday, though for now at least, Damon Harrison is signing as a member of Seattle's practice squad.
A nine-year veteran and former first-team All-Pro, Harrison, also known as "Snacks," presumably factors into Seattle's plans on the 53-man roster eventually, but having not played yet this season or taken part in training camp, he'll start out on the practice squad for the time being.
The Seahawks also made an addition to their 53-man roster, signing defensive end Jonathan Bullard. Cornerback Neiko Thorpe, who has missed the past two games with a hip injury, was placed on injured reserve.
In addition to Harrison, the Seahawks also added to the practice squad cornerback DeMarkus Acy and linebacker Michael Divinity. Receiver Lance Lenoir was released to make room on the practice squad, and on Tuesday defensive tackle Demarcus Christmas was released from the practice squad.
Harrison, 31, is best known as a run-stuffing interior lineman, but has also contributed 11 sacks in his career, 9.5 of which have come since 2016.
Harrison came into the league as an undrafted rookie out of William Penn, signing with the Jets in 2012. He appeared in only five games as a rookie, but took over a starting job in 2013 and has started 111 of 112 games played over the past seven seasons, recording 485 tackles, 37 tackles for loss, 24 quarterback hits, 11 sacks, 10 passes defensed, four forced fumbles and one interception.
Bullard, a 2016 third-round pick of the Chicago Bears, appeared in 46 games over three seasons with Chicago, starting five, then spent last season with the Arizona Cardinals, starting six of nine games played. Bullard has recorded 3.5 career sacks, 84 tackles, 13 tackles for loss and one forced fumble in 55 career games. He most recently was on Arizona's practice squad after being released as part of the cutdown to 53 players.
Acy, an undrafted rookie out of Missouri, initially signed with the San Francisco 49ers after the draft. A three-year starter at Missouri, Acy appeared in 47 games over four seasons, recording 99 tackles, three interceptions and 23 passes defensed.
Divinity went undrafted out of LSU this year and initially signed with Tampa Bay. He appeared in 29 games over four seasons, recording 105 tackles, 8.0 sacks and 17 tackles for loss.
