The Raiders entered Week 13 looking to keep their first place lead in the AFC West following wins by both the Broncos and Chiefs earlier in the day. However, the Buffalo Bills scored first on the second possession of the game as Dan Carpenter hit a 27-yard field goal to give the Bills a 3-0 lead. A Sebastian Janikowski field goal from 47 yards out, tied the game on the next possession. The Bills offense struck next as Mike Gillislee scored from one yard out to give the Bills a 10-3 lead early in the second quarter. The Raider offense managed two more Janikowski field goals, including one as the half ended to pull within one point, 10-9. To open the second half, the Bills extended their lead on a two-play drive, a 54-yard run by LeSean McCoy and a 12-yard touchdown run by Tyrod Taylor. The Raiders offense managed little on its next possession and the Bills took a 15-point lead with a Gillislee two-yard touchdown run, increasing the lead to 24-9. The Raiders five-game win streak appeared to be over, but the Raiders fought back as they had all year. On their next possession, Derek Carr, taking all snaps from the shotgun due to the injured finger he suffered in the prior game, hit Michael Crabtree on a three-yard touchdown pass to reduce the lead to 24-16. The Raiders defense forced a punt which gave the Raiders good field position at the Buffalo 38-yard line. Five plays later, Latavius Murray plunged over the goal line from a yard out to reduce the lead to one, 24-23. The Bills were again forced to punt and the Raiders offense went right down the field. Carr hit Amari Cooper on a 37-yard pitch and catch to give the Raiders the lead, 30-24. Following punts by both teams that left Buffalo at its own four-yard line early in the fourth quarter, Khalil Mack hit Taylor's arm on a pass and the ball was intercepted by Nate Allen at the Buffalo 16-yard line. Four plays later, Murray again plunged over the goal line for a three-yard touchdown run which pushed the Raider lead to 36-24. A two-point conversion pass from Carr to Seth Roberts put the lead at 14, 38-24. The Bills, however, drove the ball to the Raider 17-yard line before Mack sacked and stripped Taylor of the ball. Mack also recovered the fumble to put the game away. The 29 unanswered points to overcome the 15-point deficit was the Raiders best comeback since 1963. Carr finished with 260 yards and two touchdown passes. The win was the Raiders sixth in a row and kept the Raiders one game up on the Chiefs heading into their showdown on Thursday night. The win also put the Raiders back as the number one seed in the playoffs.. How many points did Bills score in the second half?
