The Buffalo Bills rallied from a 21-0 deficit to take down the New England Patriots 35-31 and move to within a game of their AFC East rivals.

New England were seemingly in control after Drake Maye rushed for two first-quarter touchdowns before TreVeyon Henderson ran in a 52-yard score in the second quarter.
