The Chargers hope to even their record at 2-and-2 Sunday when they play host to the Kansas City Chiefs at Qualcomm Stadium in an AFC West Division game.  The Chargers lost their second consecutive game last Sunday to the Packers in Green Bay.  Kansas City is also 1-and-2 for the season, winning its first game last weekend over the Minnesota Vikings.  San Diego and Kansas City played each other twice last year, winning one game each.  The Chargers will play the Broncos in Denver a week from Sunday, before returning home to host the Oakland Raiders on October 14th at Qualcomm.
