At home, in front of a sellout crowd for the first time since their 2009 Home Opener, the Oakland Raiders battled the Kansas City Chiefs for control of the AFC West. The first score of the game came from the Chiefs as Matt Cassel threw an 11-yard touchdown pass to Verran Tucker to take a lead over the Raiders, 7-0. After a Ryan Succop field goal, the Chiefs led the Raiders 10-0 at the half. The Raiders started the second half strong, as Jacoby Ford returned the opening kickoff 94&#160;yards for a score and cut the Chiefs' lead to 10-7. After Succop kicked yet another field goal for the Chiefs, Oakland took the lead when Jason Campbell threw a 2-yard touchdown pass to Khalif Barnes. Going into the 4th Quarter, the Raiders led 14-13. A fourth quarter Sebastian Janikowski field goal increased the Raiders' lead to 17-13. While the Raiders forced the Chiefs to punt on their next possession, punt-returner Nick Miller was charged with a controversial fumbling call. The play could not be challenged, as coach Tom Cable had used both of the Raiders' call challenges earlier in the game. On the Chiefs' ensuing drive, Cassel hooked up with Dwayne Bowe in the endzone to give the Chiefs a late 20-17 lead. In the dying seconds, the Raiders found themselves trailing until Campbell hooked up with Ford for a huge 41&#160;yard reception setting Janikowski up for the game-tying field goal. The score tied the game at 20-20, sending it into overtime. In overtime, the Raiders quickly forced the Chiefs to punt. On the Raiders' ensuing drive, Jason Campbell again hooked up with Jacoby Ford for a 47-yard pass completion. Sebastian Janikowski kicked a 31-yard field goal to give the Raiders an overtime win. With the win, Oakland went into their bye week at 5-4 and snapped a seven-game home losing streak to the Chiefs. The Raiders' win also gave them their first three-game winning streak since 2002, as well as their first winning record, at any time during a season, since 2004.
