Oakland punted for the fifth time of the second half, as the Broncos gained possession at their own 24-yard line.
Willis McGahee started off the drive with a couple of carries preceding a first-down catch by Demaryius Thomas.
Running back Ronnie Hillman then ran it three straight times to gain 18 yards, moving Denver to near midfield.
A few plays later, Matt Prater kicked a 53-yard field goal to extend the lead to 37-6. He is now 7-of-7 on the year and 2-of-2 from beyond 50 yards. He is the franchise’s all-time most accurate kicker, 97-of-119 as a Bronco.
