Denver's running game: After suffering numerous injuries to their backfield, the Broncos have turned to rookie FB Peyton Hillis, a seventh-round pick, to pick up the slack. Last week he rushed for a career-high 129 yards on 22 carries. He is looking to score for the fourth game in a row against Kansas City's 31st-ranked rush defense.
The streak: Tight end Tony Gonzalez will likely extend his reception streak to 128 games this week, as the 12-year veteran has recorded two consecutive games with at least eight catches and more than 100 yards receiving.
