The Seahawks bolstered their interior line depth by signing former Steelers center B.J. Finney.
Finney, who came into the league as an undrafted free agent out of Kansas State, has appeared in 59 games for Pittsburgh over the past four seasons, starting 13. He has seen action at center, left guard and right guard.
Finny is one of two linemen signed on Monday along with former offensive tackle Cedric Ogbuehi.
Finney's addition will give the Seahawks interior depth with centers Justin Britt and Ethan Pocic both coming off of season-ending injuries, and with last year's starting left guard Mike Iupati currently an unrestricted free agent.
