Hoping to build off their divisional road win over the Chiefs, the Raiders flew to Ralph Wilson Stadium for a Week 3 duel with the Buffalo Bills. In the first quarter, Oakland got the early lead with kicker Sebastian Janikowski getting a 23-yard and a 35-yard field goal. In the second quarter, the Bills responded with RB Marshawn Lynch getting a 14-yard TD run. The Raiders would end the half with Janikowski kicking a 32-yard field goal. In the third quarter, the Raiders increased its lead with QB JaMarcus Russell getting a 1-yard TD run. However, in the fourth quarter, Buffalo started to rally as Lynch got a 3-yard TD run. Oakland would respond as Russell completed an 84-yard TD pass to WR Johnnie Lee Higgins, yet the Bills got near as QB Trent Edwards completed a 14-yard TD pass to WR Roscoe Parrish. Later, Buffalo completed its rally as kicker Rian Lindell nailed the game-winning 38-yard field goal. After the game, Chris Mortensen of ESPN and Jay Glazer of Fox Sports both erroneously reported that Lane Kiffin would be fired the following Monday; this turned out not to be the case, as Kiffin was coaching the team during Week 4.
