Cam Newton has called Sunday's road game against the Buffalo Bills a "must win" for the New England Patriots.

The Patriots, who have lost three straight, are 2-4 and trail the Bills (5-2) in the AFC East.

"This is a must-win for us, and I'm going to control the things that I can control. I have two or three more days to prepare and that's what I plan on doing," Newton said.

The Patriots have won the division each of the past 11 seasons.
