The Chiefs are hoping that running back Jamaal Charles can surpass the 1,000-yard mark on Sunday. Charles needs to post 139 yards against Denver to reach the milestone. He has rushed for 100 or more yards in each of his last three games. "My fullbacks and offensive line are really trying to help me get there," Charles said of gaining 1,000 yards. "They're with me, the quarterback is in with me and the receivers are in with me. Everybody is in it with me and wants me to get it. I think it could be really big to build up my confidence."
