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 147 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. “This is probably the best I’ve felt since week one” said Charles. “I hope I can continue to feel like that. I’m not worrying about how many times I touch the ball. I’ve been doing this for years and it doesn’t matter to me. As long as the ball is in my hand I’m up for whatever.” NFL takes sack from Hali Scratch one of the Chiefs’ 10 sacks from last Sunday’s victory over the Oakland Raiders. The league determined that Raiders quarterback Terrell Pryor was running the ball on an option and not looking for a receiver on a fourth quarter play in which Tamba Hali was credited with a sack for tackling Pryor for a four-yard loss. So Hali’s total for the game dropped to 2 1/2 sacks. “There’s been some conviction by everybody that he was running the ball so I’m not mad at the NFL” said Hali. “They’re only doing their job and I have to make up for the lost sack I initially thought I had.” At least Hali got credit for a tackle for loss. “I did something on the play so something is better than nothing” Hali said. The Chiefs with 30 sacks for the season are still on pace for 80 which would shatter the NFL record of 72 set by the 1984 Chicago Bears.
