CB DeShawn Shead is taking a free-agent visit to Buffalo to meet with the Bills, per a league source. Shead started 15 games for the Seahawks last season and played at a high level, but he tore the ACL and meniscus in his left knee in the divisional round of the playoffs. Shead was originally a restricted free agent, but the Seahawks did not tender him, making him an unrestricted free agent. Shead, 28, also served as Seattle's special-teams captain last season. He has shown the versatility to play CB, safety and nickel during his time with the Seahawks.
