The Buffalo Bills lead the Kansas City Chiefs 10-3 following a fairly uneventful first half in New York.
Chris Hogan opened the scoring for the hosts early in the first quarter, collecting a 25-yard pass from quarterback Kyle Orton.
Andy Reid's Chiefs responded with a Cairo Santos 36-yard field goal, with the only other score before the break a Dan Carpenter kick of his own.
In a contest which has seen both sides struggle to gain big offensive yardage, running backs Jamaal Charles and Fred Jackson have been limited to just 29 and 11 yards respectively.
