(Undated) -- The Vikings addressed a concern at cornerback by signing Benny Sapp to a contract extension. Sapp became a restricted free agent last week and talked with several teams before deciding to stay with the Vikings. Last season, Sapp put in plenty of playing time when All-Pro cornerback Antoine Winfield went down with a foot injury. He finished with seven pass breakups and two forced fumbles as well as a career-high 55 tackles. The Vikings need stability in the defensive backfield after Cedric Griffin had surgery to repair a torn A-C-L, an injury that happened in the N-F-C championship game loss at New Orleans. There are reports that free agent running back Ladainian Tomlinson is ready to visit Vikings team officials tomorrow at Winter Park in Eden Prairie. The Vikings need depth at running back after Chester Taylor signed a free-agent contract with the Chicago Bears.
