The Seahawks signed defensive tackle Landon Cohen Monday, filling out the final spot on the 53-man roster that has been open since DT Travian Robertson was waived on Dec. 26.

The 28-year-old Cohen, who is listed as 6-foot-3, 300 pounds, was a seventh-round pick in 2008, and appeared in 20 games over his first two seasons in Detroit before being released after training camp in 2010. He has since spent time in Jacksonville, New England, then was out of football in 2012, spending that year running his valet parking company, according to this article on the Buffalo Bills website.

Cohen spent the 2013 season in Dallas and Chicago, starting three games for the Bears. He was with Buffalo in training camp this season but released prior to the start of the season.

Cohen has 46 tackles in 40 games plays (eight starts) over six NFL seasons. He very briefly spent time with Seattle in 2011 but did not appear in a game.

Depth on the interior defensive line could be needed this week with Jordan Hill’s status a question mark because a sprained knee.
