The 184 yards allowed were a season-low for Buffalo, and the fewest the defense has allowed since limiting Washington to 178 in a 23-0 win Oct. 30, 2011.
The Bills bounced back from a 37-31 loss at New England last weekend. And the defense was questioned after allowing a combined 1,201 yards over a two-game stretch in which the Bills were blown out 52-28 to New England and 45-3 at San Francisco.
Bills quarterback Ryan Fitzpatrick finished 17 of 27 for 168 yards. Spiller also had three catches for 39 yards, while Stevie Johnson had six catches for 79 yards.
Fitzpatrick gave much of the credit to how well the defense played.
"The defense has been working so hard," Fitzpatrick said. "There's been a lot of criticism on them, but tonight was a dominating performance and something we can build on."
