The Chiefs have reportedly agreed to contract terms with Frank Zombo, an outside linebacker who played the past three seasons with the Green Bay Packers. Zombo would be a backup for starters Tamba Hali and Justin Houston. The signing was reported by ESPN’s Adam Schefter. Zombo started eight games as a rookie in 2010 and had four sacks. He played in just 12 games over the past two seasons because of injuries. He missed the first half of last season because of a hamstring injury. The Chiefs on Wednesday also signed offensive lineman Tommie Draheim. The 6-foot-4, 309-pound Draheim was with the Packers last season during training camp as an undrafted free agent.
