The Chiefs head back to Arrowhead to take on the Arizona Cardinals tomorrow night, for each team’s second preseason game.  The Chiefs finished their training camp schedule at River Falls yesterday, and now will start working out in Kansas City.  They’re are coming off their thrilling 24-20 come-from-behind win against the Chicago Bears, as Tyler Thigpen hit Bobby Sippio for the last-second score.  The Chiefs hope to get number-one pick Glenn Dorsey back from a knee injury he sustained in practice two weeks ago, for his first work in live action.
