The Seattle Seahawks have signed veteran defensive tackle Landon Cohen to the 53-man active roster on Monday. The team had an open roster spot.

Cohen, 29, has not played this season and did not play in 2012. He played 13 games for Chicago in 2013 and two for Dallas.

This likely is a move to add depth on the defensive line if defensive tackle Jordan Hill is unable to play Saturday against Carolina after suffering a sprained knee in the regular-season finale against the St. Louis Rams.

Hill has been a real spark for the Seattle defense since nose tackle Brandon Mebane was lost for the season with a torn hamstring. Hill has 5.5 sacks in the last six games.

Cohen (6-3, 275) played college ball at Ohio University and was a seventh-round draft choice by Detroit in 2008.
