All-Pro defensive tackle Chris Jones, who has been in the midst of a contract dispute, left open the possibility that he could be on the field for the Kansas City Chiefs when they open the season on Thursday night against the Detroit Lions. Jones has been working out in Miami throughout the offseason and training camp while his agents, Jason and Michael Katz, negotiate with the Chiefs on a potential extension. Jones is entering the final year of a four-year, $80 million deal, and said in his first public comments Wednesday that he “just wants a raise” like any other employee in any line of work.
