Stephen McGee led a 65-yard drive on the yard touchdown pass to Dwayne Harris 23, in their preseason opener.
Harris finished with five catches for 127 yards and two fourth-quarter touchdowns, including one for 76 yards.
Kyle Orton played one series before giving way to Tim Tebow, completing just two of his six passes for 37 yards. Tebow, the center of a growing quarterback controversy after the Broncos failed to trade him, went 6-of-7 for 91 yards.
Brady Quinn played the second half and went 8-for-14 for 120 yards and a touchdown.
