Trying to snap a five-game losing streak, the Raiders flew to Paul Brown Stadium for a Week 14 fight with the Cincinnati Bengals.  On the third play of the game, QB Carson Palmer was intercepted by cornerback Nnamdi Asomugha, only for the Raiders to fumble the ball on the next play from scrimmage. In the first quarter, the Raiders trailed early as QB Carson Palmer completing an 8-yard TD pass to WR Chris Henry, while RB Rudi Johnson got a 1-yard TD run.  In the second quarter, following another interception by Asomugha, Oakland managed to get on the board with kicker Sebastian Janikowski getting a 33-yard field goal for the only score of the period.  In the third quarter, Cincinnati's dominance continued with Rudi getting a 6-yard TD run, while Palmer hooked up with WR T. J. Houshmandzadeh for a 20-yard TD strike, which was followed up with a missed PAT.  In the fourth quarter, the only form of a comeback the Raiders could do was QB Aaron Brooks completing a 5-yard TD pass to WR Ronald Curry.  With their sixth-straight loss, the Raiders fell to 2-11.
