The Cleveland Browns had free-agent S Ko Simpson in for a visit late this week, a source confirmed. Simpson worked out for the Browns in November. Player visits generally include a visit to the team's headquarters and a team physical. Simpson, who was selected in the fourth round of the 2006 NFL draft by the Buffalo Bills, was released by the Detroit Lions on Sept. 4, 2010. He did not play this season, but also had workouts for the Cincinnati Bengals, Indianapolis Colts and Washington Redskins during the regular season. Source: FOXSports
