Seattle Seahawks free agent left tackle Russell Okung visits the Pittsburgh Steelers on Monday. He has visited the New York Giants and Detroit Lions. Okung is representing himself, but has consulted with the NFL Players Association for contractual advice. Okung is still talking with the Seahawks. The San Francisco 49ers have shown interest.
