Chiefs coach Herm Edwards says there’s no question that Damon Huard will start at quarterback Sunday in San Diego.  But he says he might also call Brodie Croyle in for a chance at some action.  For the second day in-a-row, Larry Johnson didn’t practice yesterday.  He’s still nursing his sore hamstring.  Eddie Kennison, with a similar injury, did practice — but on a limited basis.  Edwards says both are expected to play Sunday.  Kickoff against the Chargers is set for 3:15.
