Buffalo kicker Dave Rayner connected on a 28-yard field goal, cutting the Denver lead to 7-3 just over six minutes to go in the second quarter.
A 55-yard catch and run by Stevie Johnson set up the Bills in the red zone.
But the Denver defense forced an incompletion in the end zone on third down, and the Bills brought on Rayner for the field goal.
