Chiefs Sign LB Zach Thomas

The Kansas City Chiefs added another part to their defense Saturday when they agreed to contract terms with veteran linebacker Zach Thomas. Thomas turns 36 in September, but he has made seven trips to the Pro Bowl in his 13 NFL seasons. His most recent Pro Bowl season came in 2006 with Miami, but Thomas started 14 games last year in his first season with Dallas. His first 12 NFL seasons were played with the Dolphins. Thomas is the second veteran linebacker acquired by the Chiefs in recent weeks. He follows Mike Vrabel, who came in the trade with New England that also brought quarterback Matt Cassel.
