Former Pittsburgh Steelers free safety Ryan Clark visited the Seattle Seahawks, according to a league source.
He wasn't immediately signed to a contract.
Clark has previously visited the Washington Redskins.
Clark, 34, also has drawn interest from the New York Jets.
An aggressive, hard-hitting free safety, he has played in one Pro Bowl. Clark once knocked former Baltimore Ravens running back Willis McGahee unconscious with a devastating tackle during the 2008 AFC championship game, giving him a concussion.
Clark, who has played for the Steelers in the past eight seasons of a 12-year NFL career, started every game last season, finishing with 104 tackles and two interceptions.
For his career, the 5-foot-11, 205-pound former Louisiana State standout has 827 tackles, 15 interceptions, five forced fumbles and 3.5 sacks.
