The Raiders held Buffalo to a 25-yard field goal with 2:22 left in the half after the Bills drove 70 yards in 10 plays, then marched right down the field for a touchdown on a 1-yard run by Jason Campbell for a 21-3 lead.
Buffalo moved steadily with the pass, only to have Michael Huff stop David Nelson short of a first down on a 7-yard pass to the 7-yard line. The Bills opted for Ryan Lindell and the field goal team rather than go for the first down.
The Raiders got the ball back with 2:17 left in the half and struck with a 16-yard pass from Campbell to Darren McFadden, a 42-yard sideline streak from Campbell to rookie Denarius Moore and a 22-yard run on a draw to Michael Bush to the 1. Campbell scored on the next play.
Oakland scored twice on a 1-yard run by Bush and a 5-yard run by McFadden. Stanford Routt’s interception of quarterback Ryan Fitzpatrick set up a short-field 34-yard drive for the second score.
Buffalo got the ball one last time at the end of the half and had a 39-yard field goal attempt blocked at the gun by Tyvon Branch to complete one of their better halves of football in a long time
