Chiefs add to the roster

Posted by ESPN.com's Bill Williamson

The Chiefs are busy Wednesday as they prepare to face San Diego on Sunday. The Chiefs made several roster moves, including the addition veteran cornerbacks Ricardo Colclough and David Macklin.

Both players bring valuable NFL experience to one of the young Chiefs' greenest areas. Macklin is an eight-year veteran who has played in 116 games for three teams. He was cut by St. Louis this summer. Colclough was a second-round pick of Pittsburgh in 2004.He has played in 36 games, most recently with Cleveland last season. He was cut by Carolina this summer.

Colclough and Macklin could potentially play at San Diego because of injuries to Brandon Flowers and Patrick Surtain.

Kansas City also signed defensive end Wallace Gilberry. The former Alabama star was on the New York Giants' practice squad. The Chiefs also signed running back Omar Cuff to the practice squad. The former Delaware standout was previously with Tennessee as an undrafted free agent.
