Hoping to rebound from their road loss to the Packers, the Raiders went home for a Week 15 intraconference duel with the defending Super Bowl champions, the Indianapolis Colts.  In the first quarter, Oakland trailed early as Colts kicker Adam Vinatieri managed to get a 22-yard field goal, while CB T.J. Rushing returned a punt 90 yards for a touchdown.  In the second quarter, the Raiders got on the board with QB Josh McCown completing a 3-yard TD pass to WR Ronald Curry for the only score of the period. In the third quarter, Indianapolis increased its lead with Vinatieri nailing a 19-yard field goal for the only score of the period.  In the fourth quarter, Oakland took the lead with RB Justin Fargas getting a 2-yard run.  However, the Colts sealed the win with QB Peyton Manning completing a 20-yard TD pass to WR Anthony Gonzalez. With the loss, not only did the Raiders fall to 4-10, but it also marked their 5th-straight time in which Oakland had at least 10 losses in a season. During this game Justin Fargas rushed for a season total of 1,000 yards, despite being given the starting job for nine games.
