The Patriots remained undefeated in 2015 Monday night, dumping the Bills, 20-13, at Gillette Stadium.

In one of the oddest games in recent memory, the Pats were able to come away with the victory despite a less-than-stellar offensive performance and yet more injuries coming into play. Danny Amendola, who was well on his way to a career night with nine catches for 117 yards, left the game in the second half with a knee injury. Amendola had actually looked like a suitable replacement for Julian Edelman in the first half Monday, bailing out the Patriots offense on multiple plays.

Tom Brady fought through relentless Buffalo front line pressure and went 20-of-39 for 277 yards. He threw a touchdown pass to James White and threw an interception. White also had a rushing touchdown.

The Patriots looked as though they were going to go up big on the Bills in the third quarter when Brady found a wide open Amendola, who had a clear path to the end zone. But an inadvertent whistle was called by a sideline official and the play was ruled dead. The Pats' sputtered after the play on both sides of the ball and Buffalo hung around right until the end.

New England now sets its eyes on Denver, which it will play Sunday night (8:30 p.m., NBC).
