Kansas City, Mo. ? The Kansas City Chiefs filled part of their hole at defensive tackle Friday, agreeing to re-sign Ron Edwards to a four-year deal. The deal reporedly was worth between $7 million and $8 million over the four years.

Edwards started all 16 regular-season games for the Chiefs last season and their postseason loss to Indianapolis. He had 25 tackles and 2.5 sacks after joining Kansas City as a free agent from Buffalo in 2006.

Before the Edwards deal, the Chiefs had only one experienced defensive tackle, Ryan Sims, under contract. But many expect Sims, who has underperformed, to be released before training camp.
