Don’t expect Chiefs running back Jamaal Charles’ workload to decrease on Sunday against the Houston Texans. In fact Charles may even get more work than he did last week against Oakland when Charles accounted for 128 of the Chiefs’ 216 net yards on offense. “He’s a guy who steadily wants a little more each week a little more responsibility” said offensive coordinator Doug Pederson “and the more he gets comfortable in our system and what we’re asking him to do we’ll put a little more on his plate. “He’s so explosive and we want to be able to use him in that fashion and create matchups in our favor.” Charles the AFC’s leader in yards from scrimmage with 775 yards (475 rushing 300 receiving) was a full participant in practice on Wednesday and Thursday for the first time in three weeks. Charles said the blisters on his feet are healing and he’s ready to take on an even bigger role in the offense.
